Our group is working on synthesis of active rare earth based electrocatalyst with ORR activity. We are studying the catalytic activity of transition metal doped rare earth metal oxide-carbon nanocomposites synthesized by microwave mediated method.  Changing the transition metal doping percentage, we are studying its effect on ORR activity. It is expected that the enhancement in ORR activity could be due to factors, such as; (a) electronic interaction between the hetero-metal atom dopant and metal oxide or (b) presence of multiple metal centre as active site or (c) simultaneous presence of both factors (a) and (b). 

Our group is working on the synthesis of metal oxides, vanadates nanoparticles via microwave assisted hydrothermal synthesis. Different dyes are chosen as a model pollutant to evaluate the photocatalytic activity of the prepared nanoparticles in aqueous medium under visible / UV light irradiation. Since larger part of sunlight carries visible radiation, our aim is to fabricate novel photocatalysts (by tuning the band gap) with considerable photocatalytic activity under visible light irradiation.

We are also studying the toxicology and antibacterial activity of the nanoparticles (CeO2, ZnO, CeVO4) prepared by different methods. In vitro toxicology study of the synthesized nanoceria particles has shown good free radical scavenging activity for NO and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical assayed within a concentration range of 25 to 75 ng ml−1. ZnO nanoparticles synthesized by the polyol method showed better MIC values against both Gram-positive and Gram-negative bacteria as compared to particles synthesized by aqueous precipitation method.
