英文摘要carbon supported pt-cu catalyst (ptcu/c) with surface enriched pt was synthesized by annealing the pt-deposited cu particles. x-ray diffraction (xrd) results indicate the formation of disordered pt-cu alloy phase with a high level of cu/pt atomic ratio. x-ray photoelectron spectroscopy (xps) and inductively coupled plasma (icp) analysis confirm the surface enrichment of pt. electrochemical measurements show that ptcu/c has 3.7 times higher pt mass activity toward the oxygen reduction reaction (orr) than commercial pt/c. the enhanced orr activity of ptcu/c is attributed to the modified electronic properties of surface pt atoms, which reduces the surface blocking of the orr oxygenated species. copyright (c) 2012, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
