Abstract:The catalytic activities of noble-metal electrocatalysts are heavily correlated to their defective surface structures. However, controllably constructing surface defects on noble-metal nanocrystals remains a great challenge. In this work, an electrochemical method is developed to tailor the surface structure of the PdMo nanoalloy electrocatalyst, involving H absorption followed by its subsequent release near the surface of Pd. The optimized PdMo nanoalloy electrocatalyst exhibits an oxygen reduction reaction (… Show more
