Abstract
The catalysts of Carbon supported Pt(Pt/C) and carbon supported Pt/WO3(Pt/WO3/C) were prepared with liquid phase reduction method.It was found that the catalytic activity and stability of the Pt/WO3/C catalysts were increased with the addition of WO3.When the atomic ratio of Pt and W was 1∶1,the best electrocatalytic performance of the Pt/WO3/C catalyst for the methanol oxidation was obtained.This is attributed to the larger electrochemical surface area of Pt/WO3/C and the weeker adsorption of CO towards the catalyst.
