【Abstract】 The Pt/C catalyst with amorphous and nanosized Pt was prepared through the heat decomposition of Pt carbonyl under N2 at 150℃. It was found that the onset potential and peak potential for the methanol oxidation on such catalyst are negatively shifted and that the peak current of the methanol oxidation is significantly increased as compared to the Pt/C catalyst prepared with the traditional liquid phase reaction method. Its stability of the electrocatalytic performance is also improved. It demonstrated that the preparation procedure via the carbonyl route is a good method for preparing the electrocatalyst for the methanol oxidation.更多还原
