    Transition metal oxide (TMO)-based semiconductor nanomaterials (NMs) have been progressively explored as promising substrates for surface-enhanced Raman scattering (SERS). The design and synthesis of highly stable, extremely sensitive, exceptionally selective SERS substrates, solely based on defects engineered in TMO-based NMs, have gained significant interest. This work demonstrates a simple hydrothermal route to synthesize substoichiometric V2O5-x flexible nanobelts without the use of surfactants, stabilizing agents, reducing agents, or structure-directing agents. Furthermore, the V2O5-x nanobelts proved to be highly effective as a SERS substrate for the sensitive detection of methylene blue (MB), achieving a remarkable maximum enhancement factor of up to 6.75 × 109 and a detection limit as low as the picomolar level. This performance is the best among metal oxide semiconductors and is comparable to that of noble metals, even without the presence of a “hot spot.” Additionally, the V2O5-x nanobelts demonstrate excellent selectivity as a “SERS Tweezer,” enabling the precise detection of MB even in the presence of interfering analytes across binary, ternary, and quinary mixtures. Notably, V2O5-x nanobelts successfully detected melamine and ethephon for the first time using a TMO-based SERS substrate. In addition, the detection limit for SERS using a V2O5-x substrate reached 3 ppm of melamine in liquid milk. Thus, our results clearly demonstrate that metal oxide semiconductors can be transformed into cost-effective, SERS-active substrates through defect engineering. These engineered substrates exhibit high sensitivity, selectivity, stability, recyclability, and biocompatibility?comparable to or even surpassing those of noble metal nanomaterial-based SERS substrates. This advancement could enable their effective use in detecting contaminants in foods and food ingredients.

    In this work, we designed an intrinsic self-healing hydrogel polymer electrolyte (HGPE) through a synergistic strategy that combines hydrogen bonding, dynamic covalent chemistry, and noncovalent interactions. The Zn2+ ion-induced network densification has created a non-porous, highly cross-linked hydrogel matrix with superior tensile properties, ionic conductivity, cation transference number, good oxidative stability, and, more importantly, an ultrafast self-healing behavior. The steady and dynamic rheological experiments conducted for the self-healing hydrogel polymer electrolyte have shown a healing efficiency of 93% within just 5 min. In the Zn||Zn symmetric cells, the HGPE suppresses the dendrite growth, enabling stable cycling for over 1000 h by maintaining high performance. In the coin cell, when the cell was tested with a Zn-doped MnO cathode, high discharge capacity could be achieved. The performance was further validated by integrating it into a rechargeable homemade pouch cell with a Zn-doped MnO cathode. Hence, the present work offers several promising advancements in the development of self-healing hydrogel polymer electrolytes for the flexible rechargeable zinc metal batteries.

    IF: 8.067 (2021) & 5.7 (2023) Lead-free perovskite nanocrystals (NCs) have attracted considerable attention due to their excellent optoelectronic properties. However, they generally exhibit broadband emission with poor color purity. Similarly, obtaining tunable red/green/blue (RGB) emissions from lead-free perovskite NCs is highly desirable for several display applications. However, directly synthesizing lead-free perovskite NCs with tunable RGB emission and high color purity remains challenging. Herein, we have developed a simple and rapid microwave-assisted (MW-AT) synthesis strategy for synthesizing Mn-doped CsBr [Mn2+:CsBr] to phase engineering of non-toxic and stable all-inorganic cesium manganese bromide perovskite NCs in a nonpolar solvent with tunable blue-green-red emission color with high color purity. The phase transition was triggered by changing the MnBr2 concentration during the microwave synthesis: from Mn2+:CsBr (blue emission) to zero dimensional (0D) Cs3MnBr5 NCs (green emission) to one dimensional (1D) CsMnBr3 NCs (red emission). In addition, in a controlled moisture environment, both the 0D Cs3MnBr5 and 1D CsMnBr3 NCs were transformed into 0D Cs2MnBr4·2H2O NCs (blue emission), which could be inversely transformed back to their respective original phase via thermal annealing. Thus, our work highlights for the first time a rapid and efficient MW-AT synthesis strategy to obtain phase-pure tunable optical properties with high color purity from Mn-doped CsBr to cesium manganese bromide perovskite NCs via phase engineering, which can be further utilized in designing anti-counterfeiting and encryption materials for coding with high security and information concealment. Our work also provides a new avenue for exploring efficient MW-AT synthesis of other earth-abundant eco-friendly highly luminescent Pb-free perovskite NCs for future endeavors.

    Our recently published study in ACS Catalysis describes a carefully tailored electrocatalyst for PEM fuel cell applications with a Pt-CeO2 interface built on the SiO2 substrate that performs well in the reaction even under oxygen-lean circumstances. This oxygen spillover effect is shown to be mobilized by the intervention of oxygen vacancies in the CeO2 interface created with Pt nanoparticles, which provides the necessary push for the Pt active sites towards ORR by increasing the local oxygen concentration. Aside from that, the system performs well in low humidity situations due to the self-humidification capability of the SiO2 core. The carbon-free nature of the catalyst also provides enhanced structural endurance due to its enhanced corrosion resistance. The study also includes a realistic validation of the catalyst by using it as the cathode in a working single-cell of a polymer electrolyte membrane fuel cell (PEMFC), demonstrating the system's ability to function relatively well under oxygen-lean conditions when compared to the standard Pt-supported carbon (Pt/C) catalyst.

The 3D support enabled effective ionomer infiltration, enhancing coverage, triple-phase boundary (TPB) formation, and facilitating water as well as reactant/product transport, all crucial for the CL activation.

    This work presents a design for modifying the Zn anode with a polydopamine (PDA) protective layer, followed by ultraviolet (UV) treatment, to achieve a long-cycle-life anode for zinc air batteries (ZAB). An electroless plating technique was employed to coat the Zn foil with a PDA layer (Zn@PDA), leveraging the PDA's strong adsorption on the Zn, facilitated by the formation of the bidentate bonds. UV-induced secondary modifications are conducted over the PDA-coated Zn to obtain Zn@PDA-UV electrodes with enhanced mechanical as well as chemical stability. When paired with the commercial catalysts to assemble alkaline ZABs for practical use, the battery displayed excellent cycling stability.

    The catalytic hydrogenation of CO2 to methanol using Cu-ZnO/Al2O3 (CZA) is a key route for sustainable chemical production, when coupled with CO2-rich industrial off-gases. However, trace secondary gases, though present only at ppm levels, can poison active sites and suppress catalytic performance. In this work, we employ periodic density functional theory (DFT) to investigate interactions of H2S, SO2, NO2, NO, CO and CH4 with five ZnO surfaces: (10-10), (10-11), (11-20), (10-13), and (11-22), and com- pared their adsorption pattern with CO2, the principle component of methanol synthe- sis. H2S dissociates on all the surfaces, SO2 and NO2 are chemisorbed, CH4 remains physisorbed, and NO, CO, and CO2 exhibit facet-dependent adsorption. Electronic structure analysis reveals that chemisorption occurs when surface energy states near the Fermi level overlap with the HOMO of the adsorbate, enabling charge transfer, whereas physisorption lacks such overlap. The adsorption strength follows the order: H2S > SO2 > NO2 > NO > CO ? CO2 > CH4, suggesting that sulfur and nitrogen-containing species exhibit strong chemisorption and compete with CO2 for active sites, potentially impacting the efficiency of methanol synthesis. These insights provide an atomic-scale understanding of impurity–surface interactions and highlight the potential role of ZnO as an efficient feedstock purifier for CO2-rich gas streams.

    The thermocatalytic hydrogenation of CO? to methanol over Cu/ZnO/Al?O? (CZA) catalysts offers an effective route for CO? utilization and methanol production. However, limited CO? conversion and catalyst deactivation remain major challenges. Under reaction conditions, ZnO, a crucial structural promoter in the CZA catalyst, is exposed to reactants and modulates CO? and H? activation. Despite its importance, the facet-dependent reactivity of ZnO remains poorly understood. Herein, periodic density functional theory (DFT) calculations were employed to investigate the adsorption and co-adsorption of CO? and H? on five ZnO surfaces: (101?0), (101?1), (112?0), (101?3), and (112?2). CO? physisorption on (101?1), (112?0), and (101?3) facets contributes to low conversion rates, whereas on (101?0), the formation of tridentate carbonate species blocks active sites. In contrast, the (112?2) facet stabilizes bidentate carbonate species that undergo stepwise hydrogenation to yield *COOH, *CHO, and *CH?O intermediates. Analysis of coordination, charge distribution, and projected density of states (pDOS) reveals Zn as the primary CO? activation site and O as responsible for H? dissociation.

    Metal hydrides play a pivotal role in a wide range of applications, including hydrogen storage, compression, heat management, and catalysis, making them a central focus of interdisciplinary research spanning chemistry, materials science, and engineering. The performance of the metal hydride based systems is strongly governed by the thermodynamics of metal-hydrogen interactions. Among key thermodynamic properties, the equilibrium plateau pressure (Peq ) is particularly critical, as it defines the conditions under which hydrogen absorption and desorption occur, directly influencing operating conditions of the system. Traditionally, determination of P eq requires extensive experimental measurements, limiting the pace of materials discovery. In this work, we introduce EquiP, a machine learning framework designed to predict P eq as a function of temperature. Beyond single-point predictions, EquiP generates complete Van’t Hoff plots (Peq vs. 1/T), enabling rapid determination of enthalpy (?H) and entropy (?S) of hydride formation. We further show that incorporating structural descriptors derived from X-ray diffraction (XRD) data enhances the performance of the model, with sparse training datasets. Comparative analyses demonstrate that the extended feature set improves predictive accuracy and generalises well to unseen hydride compositions. This work demonstrates that with limited data, intelligent feature design grounded in domain knowledge is the key to improving predictions of complex material properties.

    e present a machine-learning powered Metal Hydride’s Pressure-Composition-Temperature isotherm Predictor (MH-PCTpro) for metal compositions. To train the MH-PCTpro, an experimental database of PCT isotherms is built from published literature. The database comprises over 14,000 data points extracted from 237 PCT isotherms representing 138 distinct compositions. The dataset encompasses more than 25 elements and spans a broad spectrum of absorption temperatures (263–653 K) and hydrogen pressures (0.001–40 MPa). The model is validated on a wide range of alloy families and its predictions are consistent with experimental results. The model also captures temperature-dependent variations in plateau pressure, enabling determination of enthalpy and entropy of hydride formation through Van’t Hoff plots. Hence, MH-PCTpro can be used as an ML tool for guiding PCT experiments, offering PCT isotherm predictions and valuable thermodynamic insights into materials suitable for solid-state hydrogen storage.

    One of the key intricacies against using Prussian blue analogues (PBAs) in aqueous batteries is their gradual dissolution in aqueous electrolytes, resulting in inadequate cycling stability. Besides, the rate capability of PBAs is limited due to their poor electrical conductivity. To overcome these challenges, it is essential to tune the physical and chemical properties of PBAs at the nano regime without affecting the inherent charge storage properties, especially at high-voltage operating conditions. Through this work, a strategy is demonstrated to enhance the electrochemical performance of vanadium-based PBA (V-PBA) by surface engineering using a conducting polymer nano-skin (V-PBA/PPy) for aqueous zinc metal batteries. The polypyrrole (PPy) nano-skin over the V-PBA nanoparticles acts as an electron percolation path to ameliorate the poor electronic conductivity of the otherwise pristine V-PBA. Interestingly, the V-PBA with an optimized polypyrrole coating (V-PBA/PPy-2) exhibits an enhanced specific capacity (173 mAh g?1 at 0.10 A g?1) than the pristine V-PBA counterpart (80 mAh g?1) and 85% capacity retention up to 500 cycles. The DFT calculation confirms the synergistic interaction between PPy and V-PBA and the presence of PPy favors the adsorption of Zn.

    Seawater electrolysis is recognized as a promising technology to cater to the worldwide drive for sustainable hydrogen production; however, its practical viability is often hindered by the inevitable anode corrosion arising from the electrode side reactions owing to the presence of high chloride content which eventually degrade the electrode performance eventually. Herein, the design of unprecedented ammonium iron hydrogen phosphite (FeHPhi) along with a trace amount of Cu, is reported as the unique and much desired electrode material for seawater electrolysis due to its special chloride repellant nature along with great electrocatalytic activity toward water oxidation. The [HPO3]2? oxoanion as Lewis base in the structure effectively restricts chloride ions, while the Fe center acts as Lewis acid offering an active site for water oxidation, also well-supported theoretically. Leveraging this frustrated Lewis pair combination, the electrocatalyst achieves a high current density of 500 mA cm?2 at 344 mV overpotential in alkaline real seawater with impressive robustness to sustain for 200 h when operated under chlorine evolution reaction dominating region (>2 V). The electrocatalyst also demonstrates superior performance in anion exchange membrane freshwater and seawater electrolysis, demonstrating its potential applicability.

    In this investigation, we elucidated, one-pot two stage efficient synthesis of multifuctionalized spiro[oxindole ?3,3?-pyrrolidine]. The methodology proceeds via organocatalyzed nitro-Michael addition reaction between indolylidenecyanoesters and nitroalkanes to formed nitro-Michael adduct which transformed into multifunctionalized 3,3?-pyrrolidinyl-spirooxindoles by metal catalyzed reductive cyclization cascade. DFT investigations were conducted to elucidate the mechanism underlying the preferential reduction of the nitro group, with subsequent attack on the nitrile and ester groups remain inert throughout the reaction process. The approach is operationally simple, easily scalable, exhibits compatibility with readily accessible starting material and catalysts, thereby emphasizing cost-effectiveness.

    In this work, we show that employing retrieval augmented generation (RAG) with a large language model (LLM) enables us to extract accurate data from scientific literature and construct datasets. The rapid growth in publications necessitates the automation of the extraction of structured data, as it is crucial for training machine learning(ML) models. The pipeline developed is simple and can be adjusted accordingly with natural language as input. Quantization enables us to run LLMs on consumer hardware and remove the reliance on closed-source models. Both Llama3-8B and Gemma2-9B with RAG give structured output consistently and with high accuracy as compared to direct prompting. Using the newly developed protocol, we created a data set of metal hydrides for solid-state hydrogen storage from paper abstracts. The accuracy of the generated dataset was 88% in the cases tested. Further, we demonstrate that the generated dataset is ready-to-use for ML models by testing it with HYST to predict the H at a given temperature. Thus, we demonstrate a pipeline to create datasets from scientific literature at minimal computational cost and high accuracy.

    IF: 8.8; Electrocatalytic water splitting to hydrogen and oxygen is considered to be one of the significant routes for future renewable energy conversion. Therefore, the development of unique, efficient, and cost-effective bifunctional electrocatalysts, which can perform both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), is critical for the accessible utilization of renewable energy. The increasing overall efficiency of the water-splitting reaction is pivotal for sustainable energy conversion and hydrogen production. Herein, we present a facile solution-based synthesis route to control the crystallinity of the cobalt tungstate (CoWO4) nanomaterials to amorphous, semiamorphous, and crystalline phases and further exploit these nanomaterials as bifunctional electrocatalysts for the HER, OER, and overall electrochemical water splitting reaction. Notably, the semiamorphous cobalt tungstate nanomaterials show a remarkable surface area of approximately 150 m2/g, the highest reported for CoWO4-based materials, and demonstrated superior activity for both the OER and HER and outstanding stability over the amorphous and crystalline counterparts. Notably, the SemiAmp||SemiAmp electrolyzer demonstrated a better performance for overall water splitting than the commercial RuO2||Pt/C electrolyzer.

    IF: 6.4; The Cover Art associated with the manuscript has been selected as the Front Cover for ACS Applied Energy Materials. https://pubs.acs.org/toc/aaemcq/7/4 We report a simple inorganic route for synthesizing a Pd/WO3 3D hollow sphere nanocatalyst, where Pd nanoparticles are encapsulated and well distributed on porous tungsten oxide nanospheres. The synthesis protocol has advantages, as it requires no surfactant or stabilizing agent, Pd loading is easily tuned, and the as-synthesized nanomaterials can be directly used as catalysts for the CO oxidation reaction. The synthesized nanocatalyst exhibited 100% CO to CO2 conversion efficiency at 260 °C. In addition, the nanocatalyst demonstrated remarkable SO2 (3 ppm) tolerance during the CO oxidation reaction for prolonged SO2 sulfation of 1–21 h at 260–400 °C. This represents the longest SO2 exposure time reported to date based on a single metal Pd/support-based nanocatalyst. No decrement in CO conversion efficiency was observed even after SO2 (3 ppm) treatment for 21 h for the first time based on a single metal Pd-based nanocatalyst. Moreover, the synthesized nanocatalyst shows H2S (4 ppm), even in situ H2S tolerance during the CO oxidation reaction at 260 °C for 1–3 h and exhibited less sensitivity to prolonged and stringent sulfur exposure, with the highest H2S concentration and maximum 100% CO to CO2 conversion efficiency obtained after H2S treatment for the first time based on a Pd-based nanocatalyst to the best of our knowledge. The composition and structure of the R-Pd/WO3 nanocatalyst were not much influenced, even after the prolonged SO2 and H2S exposure during the CO oxidation reaction, as verified from spent catalyst analysis. Finally, our DFT-based model provides insights into understanding the observed sulfur resistance on Pd/WO3 by analyzing the underlying electronic structure. Therefore, our strategic synthesis methodology will open up many opportunities to select Pd/metal oxide-based nanomaterials for designing highly efficient, stable, and SO2/H2S-resistant nanocomposite catalyst.

    Zinc anode deterioration in aqueous electrolytes, and Zn dendrite growth is a major concern in the operation of aqueous rechargeable Zn metal batteries (AZMBs). To tackle this the replacement of aqueous electrolytes with a zinc hydrogel polymer electrolyte (ZHPE) is presented in this study. This method involves structural modifications of the ZHPE by phytic acid through an ultraviolet (UV) light-induced photopolymerization process.

    Our new paper published in ACS Applied Engineering Materials. In this study, we created an electrocatalyst for the electrochemical oxygen reduction reaction using PtNi/SiO2 alloy as a feasible carbon-free catalyst for proton exchange membrane fuel cells (PEMFCs). One significant problem reducing the fuel cells' lifespan is carbon corrosion. The present catalyst turns out to be electrochemically more active as a potential carbon-free substitute for PEMFC applications because of the electronic level modulations brought about by lattice compression.

    For the first time, we have synthesized lead (Pb)-free manganese (Mn)- and copper (Cu)-based hybrid organic?inorganic perovskite (HOIP) compounds, compound 1, (TEA)2MnBr4, compound 2, (TBA)2MnBr4, compound 3, (TEA)2CuBr4, and compound 4, (TBA)CuBr2 (where TEA is tetraethylammonium and TBA is tetrabutylammonium), under ambient conditions via mechanochemical synthesis methodology using a Kakuhunter-made planetary mixer. The compounds are characterized as 2D except for (TBA)CuBr2, which has crystallized in the 0D lattice. The synthesized compounds are phase pure and show a stable solid-state emission at room temperature. The Mn-based perovskite compound 1 showed excellent environmental photostability for over a month and reasonable stability under a relative humidity of 70-80%. The nanoparticle (NP) dispersions of compounds 1 and 2 were used further for fluorescence titration studies using various heavy metal cations, including transition metals and lanthanides (e.g., Y3+, Nb3+, Co2+, Ni2+, Ag+, Zn2+, Cd2+, Pb2+, Gd3+, and Dy3+), where they showed good fluorescence switching by the Pb2+ ion. Compound 1 demonstrated excellent fluorescence switching performance with Pb2+ titration with a Pb2+ detection limit of 2.43 × 10-8 M and hence can be used to fabricate a Pb2+ calorimetric sensor. A preliminary visual thin film-based sensor using NPs of compound 1 was fabricated to test the change in emission from blue to green in correlation with the results obtained in the NP solution during Pb2+ ion sensing. A fascinating in situ ion-exchange-based mechanism for the sensitivity of NPs of compound 1 is confirmed. This study reveals the ability of Pb-free Mn-based HOIPs to detect an oxidizing metal cation, Pb2+, efficiently and quantitatively

    We present a machine learning (ML) framework HEART (HydrogEn storAge propeRty predicTor) for identifying suitable families of metal alloys for hydrogen storage under ambient conditions. Our framework includes two ML models that predict the hydrogen storage capacity (HYST) and the enthalpy of hydride formation (THOR) of multi-component metal alloys. We demonstrate that a chemically diverse set of features effectively describes the hydrogen storage properties of the alloys. In HYST, we use absorption temperature as a feature which improved H2wt% prediction significantly. For out-of-the-bag samples, HYST predicted H2wt% with R2 score of 0.81 and mean absolute error (MAE) of 0.45 wt% whereas R2 score is 0.89 and MAE is 4.53 kJ/molH2 for THOR. These models are further employed to predict H2wt% and H for 6.4 million multi-component metal alloys. We have identified 6480 compositions with superior storage properties (H2wt% 2.5 at room temperature and H 60 kJ/molH2). We have also discussed in detail the interesting trends picked up by these models like temperature dependent variation in the rate of hydrogenation and alloying effect on H2wt% and H in different families of alloys. Importantly certain elements like Al, Si, Sc, Cr, and Mn when mixed in small fractions with hydriding elements like Mg, Ti, V etc. systematically reduce H without significantly compromising the storage capacity. Further upon increasing the number of elements in the alloy i.e from binary to ternary to quaternary, the number of compositions with lower enthalpies also increases. From the 6.4 million compositions, we have reported new alloy families having potential for hydrogen storage at room temperature. Finally, we demonstrate that HEART has the potential to scan vast chemical spaces by narrowing down potential materials for hydrogen storage.

    Partial oxidation of methanol to value-added products presents an intriguing and challenging process. Among these products, formaldehyde is the simplest and one of the most vital aliphatic aldehydes, with extensive application across various domains. Industrially, silver and iron-molybdenum oxides are used as catalysts for converting methanol to formaldehyde at elevated temperatures (600? C and 250-400? C, respectively). However, in this computational and experimental study, we have demonstrated the efficacy of ZnO as a catalyst. Notably, in the presence of ZnO, methanol readily converts to formaldehyde even under ambient conditions. We employed periodic density functional theory (DFT) to explore the (1011) facet of ZnO to elucidate its interaction with methanol. Our comprehensive analysis identified the most active facet (1011) involved in the spontaneous conversion of methanol to formaldehyde. Subsequently, experimental validation supported our theoretical findings, demonstrating the conversion of methanol to formaldehyde with 100% selectivity at room temperature and atmospheric pressure in the presence of ZnO. This study exemplifies the pivotal role of theory in catalyst design.

    In this work, we introduce the HyStor database, consisting of 1280 metal alloys along with their hydrogen storage capacities (H2wt%) as a function of absorption temperature. Given the lack of updates in the existing open-access HydPark database since 2002, we sourced compositions from recent research articles and various patent documents, resulting in a total of 468 compositions. The addition is reflected in the data across all existing classes of alloy compositions, and low entropy alloys (LEA), medium entropy alloys (MEA), and high entropy alloys (HEA) have been included. This has broadened the scope of the database to encompass the latest materials of interest for hydrogen storage. HyStor contains a representation of 54 elements, with a temperature range of 200-800K and an H2wt% range of 0.1-7.19. To ensure data quality, we conducted thorough checks for duplicate entries, erroneous data, and conflicting compositions within the database. Furthermore, we conducted multiple tests to identify potential outlier compositions by benchmarking the database against the pre-trained HYST model on HydPark data. After eliminating these potential outliers, we successfully improved the error metrics of the HYST model, reducing the Mean Absolute Error (MAE) from 0.32 to 0.28 and increasing the R2 score from 0.78 to 0.82. We also tested individual classes and observed that the performance of the HYST model has increased for the majority of the classes.

    IF: 5.3 Metal ferrite (MFO) M2+Fe2O4 (M2+ = Mn, Co, Ni, and Zn) nanocrystals (NCs) with a controlled size of ~4 nm were synthesized using stearic acid as the capping agent via a facile solvothermal method. The as-synthesized MnFe2O4 (MnFO), CoFe2O4 (CoFO), NiFe2O4 (NiFO), and ZnFe2O4 (ZnFO) NCs were characterized by XRD, FT-IR, Raman, XPS, TGA, TEM, and HRTEM analyses. The electrocatalytic oxygen evolution reaction (OER) is significant for future renewable energy to produce pure hydrogen (H2) fuels through H2O splitting. However, because of the complex proton-coupled multielectron transfer process, it is kinetically quite challenging. Fe-containing transition metal-based electrocatalysts are well studied since it has been observed that Fe has a significant role in enhancing OER activity. It is wellknown that the size and shape of the Fe/ferrite-based nanoelectrocatalyst play a vital role in electrocatalysis reactions. However, it is also critical to understand the effect of other earth-abundant and cost-effective transition metal ions (e.g., Mn, Co, Ni, and Zn) combined with Fe/ferrite NC-based OER electrocatalytic reactions while keeping the size of NCs constant and compare their electrocatalytic properties toward the development of advanced nanoelectrocatalysts, which is rarely studied to the best of the authors knowledge. Therefore, herein, the electrocatalytic properties for OER were examined by using the as-synthesized MnFO, CoFO, NiFO, and ZnFO NCs to understand the effect of metal ions (Mn, Co, Ni, and Zn) on the Fe-based nanoelectrocatalysts by keeping the size of the nanoelectrocatalysts constant at ~4 nm. Additionally, the influence of different substrates, e.g., carbon paper (CP) and nickel foam (NF), on the electrocatalytic activity of MFO (MnFO, CoFO, NiFO, and ZnFO) NCs was also compared. Interestingly, as an OER nanoelectrocatalyst, the CoFO NCs on the CP substrate show better electrochemical OER activity than other MFO NCs, with a Tafel slope value of 49.4 mV dec-1, an ECSA of 112 cm2, and a long-term stability of 24 h, which is comparatively higher than the other as-synthesized MFO NCs. On the other hand, MnFO NCs on the NF substrate show better electrochemical OER activity than the other as-synthesized MFO NCs. Therefore, this work highlights the effect of the substrate and the influence of transition metals, e.g., Mn, Co, Ni, and Zn, on size-controlled Fe-based nanoelectrocatalysts toward developing advanced OER electrocatalysts.

    CO$_2$, a well-known greenhouse gas, is a potential raw material that can produce various chemicals. Dissociation of CO$_2$ to CO or hydrogenation to formate (HCOO$^*$) or carboxyl (COOH$^*$) intermediate is crucial in determining the reaction pathway for CO$_2$ conversion. In this work, we demonstrate that alloys of Mg-Cu exhibit greater activity toward activation and hydrogenation of CO$_2$ than transition metal alloys reported so far. Two different compositions of Mg-Cu, namely Mg$_2$Cu and MgCu$_2$, have been studied using periodic Density Functional Theory (DFT). Our investigations reveal that CO$_2$ chemisorbs on both intermetallic alloys. Coadsorption of CO$_2$ with H$_2$O leads to the spontaneous formation of COOH$^*$ over Mg$_2$Cu(224), whereas a negligible barrier (0.04 eV) is observed for MgCu$_2$(311). HCOO$^*$ formation has a barrier of 0.34 eV and 0.42 eV on Mg$_2$Cu(224) and MgCu$_2$(311), respectively. Dissociation of CO$_2$ to CO is kinetically unfavourable on both compositions of Mg-Cu. We provide a rationale for the observed activity by analyzing the electronic structure. Notably, the spontaneous hydrogenation of CO$_2$ makes earth-abundant metals suitable candidates for alloying that await experimental verification.

    Methane is a major constituent of natural gas and is widely used in hydrogen production. However, its high symmetry poses a challenge, as breaking the strong C-H bond requires substantial energy input. Hence, there is a pressing need to develop efficient catalysts for methane conversion. By synergizing theory and experimentation, the search for a better catalyst can be accelerated, potentially boosting methane conversion processes. In the present work, theoretical findings prompted the experiments, which revealed the spontaneous dissociation of CH4 on selected facets of ?-Ga2O3. Additionally, the activation barrier for ethane formation was merely 0.1 eV. NTP-assisted conversion of methane in the presence of ?-Ga2O3 confirmed these findings. The formation rate of hydrogen and ethane rises to 366 µmolg?1h?1 and 86.62 µmolg?1h?1, respectively, in the presence of ?-Ga2O3, in contrast to 281.4 µmolg?1h?1 and 66 µmolg?1h?1 without catalysts. For the CH4-H2O reaction in the presence of ?-Ga2O3, there is an increase of 74.42% in the CO formation rate compared to the reaction without the catalyst. An electronic structure analysis revealed that electrophilic oxygen species on the ?-Ga2O3 (-202) surface play a vital role in the decomposition of methane, facilitating C-H bond cleavage.

    Extensive research has contributed to a better understanding of the commercially important epoxidation reaction. Selectivity, a crucial aspect of this reaction, has received significant attention in both experimental and theoretical investigations. However, a consensus regarding the role of electrophilic oxygen in epoxidation is yet to be reached. The present study is a theoretical examination of the prerequisites necessary for direct epoxidation to occur on the Ag(100) surface, at varied monolayer concentrations. Additionally, the study investigates the characteristics of various oxygen species interacting with ethylene to promote the direct epoxidation pathway. Based on the effective charges and projected density of states (pDOS) analysis, three oxygen variants were identified on the Ag(100) surface: atomic oxygen, dissociatively adsorbed molecular oxygen, and O . The investigation reveals that all oxygen species, despite their physical and electronic differences, are electrophilic and undergo direct epoxidation. This work provides insights into the complex nature of epoxidation reaction and discusses electronic factors influencing the selective oxidation route on different Agsingle bondO complexes.

    CO2, a byproduct from various industrial reactions, must not be released into the atmosphere and should be managed through capture, conversion, and utilization. The first step in converting CO2 into valuable products is to break the C–O bond. This work focuses on designing Single Atom Catalysts (SACs) by doping Cu(211) surface with 13 different s, p, and d block elements with an aim to minimize the activation barrier for C–O bond cleavage. Our work demonstrates that SACs of Mg/Al/Pt@Cu(211) favour CO2 chemisorption compared to Cu(211) where CO2 physisorbs. The barrier for CO2 dissociation is lowest for Mg@Cu(211) and it increases in the order Mg@Cu(211), Al@Cu(211), Pt@Cu(211), Zn@Cu(211) Ga@Cu(211) Cu@Cu(211) Pd@Cu(211). These findings suggest that doping Cu(211) with earth-abundant metals like Mg can potentially be a viable catalyst for CO2 conversion, providing a promising solution to reduce carbon footprint and mitigate climate change.

    We report a simple inorganic route for synthesizing a Pd/WO3 3D hollow sphere nanocatalyst, where Pd nanoparticles are encapsulated and well distributed on porous tungsten oxide nanospheres. The synthesis protocol has advantages, as it requires no surfactant or stabilizing agent, Pd loading is easily tuned, and the as-synthesized nanomaterials can be directly used as catalysts for the CO oxidation reaction. The synthesized nanocatalyst exhibited 100% CO to CO2 conversion efficiency at 260 °C. In addition, the nanocatalyst demonstrated remarkable SO2 (3 ppm) tolerance during the CO oxidation reaction for prolonged SO2 sulfation of 1–21 h at 260–400 °C. This represents the longest SO2 exposure time reported to date based on a single metal Pd/support-based nanocatalyst. No decrement in CO conversion efficiency was observed even after SO2 (3 ppm) treatment for 21 h for the first time based on a single metal Pd-based nanocatalyst. Moreover, the synthesized nanocatalyst shows H2S (4 ppm), even in situ H2S tolerance during the CO oxidation reaction at 260 °C for 1–3 h and exhibited less sensitivity to prolonged and stringent sulfur exposure, with the highest H2S concentration and maximum 100% CO to CO2 conversion efficiency obtained after H2S treatment for the first time based on a Pd-based nanocatalyst to the best of our knowledge. The composition and structure of the R-Pd/WO3 nanocatalyst were not much influenced, even after the prolonged SO2 and H2S exposure during the CO oxidation reaction, as verified from spent catalyst analysis. Finally, our DFT-based model provides insights into understanding the observed sulfur resistance on Pd/WO3 by analyzing the underlying electronic structure. Therefore, our strategic synthesis methodology will open up many opportunities to select Pd/metal oxide-based nanomaterials for designing highly efficient, stable, and SO2/H2S-resistant nanocomposite catalyst.

    The rational design of noble metal-free electrocatalysts holds great promise for cost-effective green hydrogen generation through water electrolysis. In this context, here, we demonstrate the development of a superhydrophilic bifunctional electrocatalyst, that facilitates both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in alkaline conditions. This has been achieved through the in-situ growth of hierarchical NiMoO4 @CoMoO4.xH2O nanostructure on nickel foam (NF) via. a two-step hydrothermal synthesis method. NiMoO4@CoMoO4.xH2O/NF facilitates OER and HER at the overpotentials of 180 and 220 mV, respectively, at the current density of 10 mA cm-2 .

    Steam methane reforming reaction was carried out in a dielectric barrier plasma reactor. A systematic study is conducted to understand the influence of input power, flow rate, and water for the conversion, yield, and selectivity of the reaction over strategically designed catalysts. In particular, the production rate and selectivity of the products (H2, CO and C2 hydrocarbons) are monitored. CeO2 was used as packing material, mixed with oxides of manganese or copper and their combination. The optimum Cu/CeO2 catalyst illustrated the production rate of 248.7 ?molg?1h?1 and 11.25 ?molg?1h?1 for H2, and CO, respectively at specific energy input of 19.8 JL-1. DFT calculations exhibit apparent change in electronic structure of the CeO2 after inclusion of oxides of manganese and copper that enhance interaction with methane. Based on these findings, a plausible mechanism is elucidated which can help to design catalyst for other applications in non-thermal plasma atmosphere.

    The generation of low-energy 3D structures of metal clusters depends on the efficiency of the search algorithm and the accuracy of inter-atomic interaction description. In this work, we formulate the search algorithm as a reinforcement learning (RL) problem. Concisely, we propose a novel actor-critic architecture that generates low-lying isomers of metal clusters at a fraction of computational cost than conventional methods. Our RL-based search algorithm uses a previously developed DART model as a reward function to describe the inter-atomic interactions to validate predicted structures. Using the DART model as a reward function incentivizes the RL model to generate low-energy structures and helps generate valid structures. We demonstrate the advantages of our approach over conventional methods for scanning local minima on potential energy surface. Our approach not only generates isomer of gallium clusters at a minimal computational cost but also predicts isomer families that were not discovered through previous density-functional theory (DFT)-based approaches.

    We have investigated various Zn-based catalysts for their interaction with methanol (MeOH). MeOH is one of the most critical molecules being studied extensively, and Zn-based catalysts are widely used in many industrially relevant reactions involving MeOH. We note that the same element (Zn and O, in the present study) exhibits different catalytic activity in different environments. The changing environment is captured in the underlying electronic structure of the catalysts. In the present work, we compared the electronic structure of Zn-based systems, i.e., ZnAl2O4 and ZnO along with oxygen preadsorbed Zn (O-Zn) and metallic Zn. We demonstrate the one-to-one correlation between the pDOS of the bare facet and the outcome of that facet’s interaction (i.e. either adsorption or dissociation of MeOH) with MeOH. These findings would pave the way towards the in-silico design of catalysts.

    IF: 6.14; In this study, we report a simple inorganic route for the synthesis of Ru/W18O49 self-assembled coral-like nanostructures, with the following advantages: It is one step and requires no surfactant or stabilizing agent; Ru loading is easily tuned, and the as-synthesized nanomaterials can be used as a catalyst without any further processing. The preliminary investigations of the catalytic performance of these as-synthesized Ru/W18O49 nanomaterials appear quite promising for converting glucose to glycols. The total glycol selectivity of 82.6% with 100% conversion of glucose was obtained over 0.03 wt % Ru loading on tungsten nanostructures, which turns out to be the lowest Ru loading% on support reported to date to achieve the highest total glycol selectivity among the previously reported catalyst based on Ru-nano/composite materials. Additionally, preliminary results show that the concentration of Ru on W18O49 significantly affects the selectivity of the glycol production. Thus, our methodology will open up a wide range of opportunities regarding the choice of metals, stoichiometric/nonstoichiometric WOx (x=1–3) as support, and the viability of further catalytic manipulations. A probable catalytic mechanism for this catalytic process is also proposed.

    How to achieve unassisted, economical, scalable, and sustainable artificial photosynthesis for liquid fuels/products with improved solar-to-fuel efficiency (STFE) to address a carbon-neutral economy remains a big question. To a large degree, the extent of charge separation at heterojunction interfaces and charge utilization determine the STFE. Towards this, BiVO3 is assembled from ionic-precursors into TiO2 pores, and integrated structurally and electronically with TiO2 on calcination as BiVO4 quantum dots (BVQDs). BVQDs in TiO2 (BVT) pores lead to an all-inorganic system with a sub-quadrillion number of heterojunctions in a 1 cm2 device (contains ?25 ?g of BiVO4 (?2.5 wt%) in the nanopores of ?975 ?g of TiO2 (?97.5 wt%)) and facilitate artificial photosynthesis. We demonstrate 31–38% STFE with a photon to chemical conversion turn over frequency (ToFP2C) of 2.73 s?1 with a 1 cm2 wireless BiVO4–TiO2 artificial leaf (BVT-AL) device for HCHO and CH3OH. The sequential nature of CO2 reduction to HCHO and then to CH3OH is evident from the reaction results. 13CO2 isotopic labeling experiments confirm that the input CO2 is the source for product formation. A large increase in the photocurrent density and incident photon-to-current efficiency (IPCE) of BVT, over 100% for the BiVO4 photoanode in visible light, demonstrates and supports efficient visible light absorption, charge separation and migration to the redox sites. A device has been demonstrated to show sustainable activity in direct sunlight, and addresses scalability from 1 to 9 cm2. Assuming no change (50% decrease) in the STFE, a 6.74 m2 device is expected to convert 1 (0.5) kg h?1 CO2 into C1-oxygenates in sunlight. DFT calculations carried out with anatase TiO2 (101) and BiVO4 (121) interfaces support many of the experimental findings, including electron flow from the latter to the former, and interaction of the oxygen of TiO2 with BiVO4 and vice versa at the interface towards forced heterojunctions.
