Summary of Activities/Interests
Our research efforts in recent years have focused on the topics related to semiconductor & metal nanoclusters, photoresponsive organic-inorganic hybrid nanoassemblies, solar cells 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-graphene composites is a significant contribution towards the development of novel heterogeneous systems for light energy conversion.
