A platinum-tungsten oxide binary electrocatalyst, Pt-WO3, has been prepared on a carbon black support to examine the effects of the introduction of WO3 on the anodic oxidation of ethanol at Pt electrocatalyst. Specific activity for the ethanol oxidation, evaluated from voltammetric responses, was higher at the catalyst deposited on the oxide, Pt-WO3/C, than at the catalyst without the oxide, Pt/C. However, no improvement in the continuous activity was observed for the catalyst with WO3, suggesting that the effect of WO3 introduction was limited to the initial step of the anodic oxidation of ethanol at the Pt electrocatalyst.
