Prepration of Carbon-Supported PtRuMo Catalysts and the Activity for the Electrooxidation of Methanol
Abstract:
The electrooxidation of methanol on a carbon-supported PtRuMo catalysts prepared by liquid-phase NaBH4 reduction method has been investigated. The stripping current of saturated-adsorption CO is defined as normalization activity toward methanol oxidation. The effects of methanol concentration and temperature on the catalytic activity in a half-cell containing sulfuric acid electrolyte was studied. The optimal molar ratio of Pt to Ru to Mo was found to be 1:0.5:1. The catalyst had high activity at ambient temperature and its activity increased with the increase of temperature. The optimal methanol concentration was 1.0~2.0 mol/L at ambient temperature.
