Monodisperse nanoparticles (NPs) are used to investigate specific metal-support interactions. Catalytic activity and the selectivity are significantly changed depending on the type of oxide NPs in Pt catalyzed methanol oxidation. Pt NP catalysts deposited on MnO, Fe3O4, Co3O4, Cu2O, and ZnO NPs show turnover frequency comparable to Pt NP itself, but the Pt-TiO2 NP catalysts enhanced reaction rate with preferential selectivity toward partial oxidation products in methanol oxidation. Density functional theory calculation demonstrates that the charge transfer at the Pt-TiO2 interfaces is responsible for catalytic performance.
