Sintering and agglomeration of active metal nanoparticles and consequent deactivation is one of the most severe problems in industrial and environmental catalysis. We address this by encapsulating ultra small clusters in porous matrix and the nanopartciles are stabilised at 3 nm at high temperatures of the order of 750 oC. Different morphologies also are encapsulated in mesoporous compounds.
We use surface modified ultra small clusters for bacterial detection and other biological systems.
We exploit our expertise in Solid State Chemistry and structural evaluation of structured materials to design stable materials for various processes like (i) Hydrogen generation for fuel cells (ii) low temperature fuel cells (iii) O2/N2 separation for efficient combustion. We also find out structural details from powder X-ray diffraction.
We also work in engineering nanocatalysts as well as solid state materials for hydrogen generation utilizing solar energy.
We work in the fabrication of ceramic hollow fiber membranes as catalytic support for environmental catalysis and dense ceramic membranes are studied as transport membranes
We are intersted in room-temperature and high temperature electrochemistry of structured metal oxides. The material tuned with catalytic sites and oxygen vacancies are monitored as candidate for energy systems like IT-SOFC, PEMFC, URFC, Batteries etc. We are also interested in the electrochemical utilisation of CO2 and N2 reduction to value added chemicals
