Research Interests
Our research efforts in recent years have focused on the topics related to semiconductor & metal nanoclusters, photoresponsive organic-inorganic hybrid nanoassemblies, fuel cells, environmental remediation and surface photochemistry and radiation chemistry. The main emphasis of our research is to elucidate the mechanistic and kinetic details of charge transfer processes in heterogeneous assemblies with an objective to improve energy conversion efficencies. Our recent work in the area of chromophore functionalized metal nanoparticles and improved catalytic activity of semiconductor-metal composites is a significant contribution towards the development of novel heterogeneous systems for light energy conversion.
Nanoparticles and Advanced Materials: Metal and semiconductor nanostructures, Molecular Clusters & Carbon Nanotubes - Synthesis, characterization, and surface functionalization, Optical properties, Photoelectrochemistry; and Sensor applications.
Light Energy Conversion: Design of inorganic-organic nanoassemblies for light energy conversion, Organic photovoltaics
Fuel cell and Hydrogen production: Carbon nanostructures (Carbon nanotubes and fullerenes) and metal nanoparticles for the developement of fuel cell electrodes and semiconductor metal composites for photocatalytic hydrogen production
Chemical Processes in Heterogeneous Media: Surface photochemical processes, molecular clusters, ultrafast photophysical and photochemical events in oxides and polymers, mechanism and kinetics of photoeffects at semiconductor/electrolyte interface.
Environmental Science: Advanced oxidation processes for treating organic wastes from water - use of metal oxide semiconductors such as TiO2, SnO2 and ZnO to sense and degrade haloaromatics and azo dyes. Simultaneous sensing and destruction of low level toxic organics.
