dc.description.abstractThe methanol electrooxidation behaviors on commercial carbon supported Pt and PtRu catalysts in acid solution were compared by carrying out electrochemical studies. The potentiodynamic and potentiostatic experimental results showed that the PtRu/C has a higher electrocatalytic activity for the electrocatalytic oxidation of methanol than the Pt/C. Alloy formation of Ru with Pt not only modified the characteristics of H-2 adsorption on the surface of catalyst but also shifted cathodically the reduction peaks of metal oxide on the cathodic sweep with respect to Pt/C. The interaction of CH3OH with Ru is a temperature-activated process requiring elevated temperature.zh_CN
