Research Description

My research focuses on the NMR study of surface structure-catalytic activity correlations in nanoparticle catalysts and adsorbed gas molecules. In recent work, we made the first measurement of surface diffusion of CO molecules adsorbed on Pt nanoparticles using an NMR technique. Current project is aimed at developing chalcogenide nanoparticle catalysts for oxygen reduction reaction in fuel cells.
