RESEARCH FOCUS:
Development of materials to catalyze the oxidation of small organic molecules and reduction of molecular oxygen is of extreme importance in the context of sustainable energy production. Chemistry extends a great help to solve the key issues in the current energy technology practices. From the past one decade, we are actively involved in the development of electrocatalytic materials in nanosize regime for clean energy conversion reactions by utilizing the chemical synthesis principles. Of particular interest is to fabricate bimetallic nanoparticles with various architectures like alloy and core-shell type deposited on carbon-based supports. Our future work is largely aimed at fabricating Pt-M (M= Pd, Au, Ru) bimetallic nanoparticle electrocatalysts with core-shell structures anchored to a 2D-graphene and understanding these catalyst activities towards methanol oxidation reaction (MOR), oxygen reduction reaction (ORR) and formic acid oxidation reaction (FAOR).
