Abstract: The catalysts Pt/WC and Pt/WC/TiO2 were prepared by reduction-carbonization and impregnation- reduction. The phase structure of catalysts Pt/WC/TiO2 was characterized by X-ray diffraction and the morphology of the TiO2 and Pt/WC/TiO2 were observed by Scanning Electron Microscopy. The cyclic voltammogram( CV) of the methanol oxidation on Pt/WC and Pt/WC/TiO2 catalysts showed that the better performance of Pt/WC/TiO2 catalyst than that of the Pt/WC catalyst for methanol oxidation in terms of the onset potential and peak current. And the Pt/WC/TiO2 catalyst was fairly stable to CO of the catalyst. The chronoamperometry results demonstrated that the Pt/WC/TiO2 yielded higher electrocatalytic activity comparing with Pt/WC catalyst.
