Carbon-supported Ptshell-Pdcore electrocatalyst was synthesized by electroless deposition and galvanic displacement. The catalsyt was active and suitable for oxidation of both methanol and ethanol. The stability of Ptshell-Pdcore toward alcohol oxidation was attributed to the modified electronic characteristics of the Pt overlayer in the Ptshell-Pdcore, leading to its weak binding with COad. The binding property of the surface Pt with COad, and the facile oxidation of COad by OHad were investigated by X-ray spectroscopy, and by successive COad-stripping experiment, respectively. |
