Our research focuses on the innovative design and synthesis of advanced nanomaterials, including Perovskites, Semiconductors, Plasmonic oxides, metal-semiconductor composites, polymer composites, Metal-Organic Frameworks (MOFs), and Covalent Organic Frameworks (COFs). By utilising their unique structural, optical, and electronic properties, we aim to develop cutting-edge solutions for energy and environmental challenges. We employ advanced wet chemical techniques for precise bottom-up synthesis, enabling fine control over material composition, morphology, and functionality. These tailored nanomaterials are optimized for high-performance applications, including optoelectronics, Surface-Enhanced Raman Scattering (SERS), sensing technologies, heterogeneous catalysis, photocatalysis and water splitting. Our research also extends to energy storage, CO₂ reduction, and environmental remediation, where MOFs, COFs, and plasmonic-semiconductor composites play a crucial role in sustainable solutions. By integrating innovative material design with advanced characterization approaches, we strive to push the boundaries of materials science, driving the development of next-generation technologies for a sustainable and energy-efficient future.
