Abstract

Abstract:

The promoting action of phosphotungstic acid(PWA) in the electrolyte on the oxidation of formic acid at the carbon supported Pt(Pt/C) catalyst was investigated via EDS, XRD and electrochemical methods. It was found that PWA can increase not only the electrocatalytic activity of the Pt/C catalyst electrode for the oxidation of formic acid, but also the electrocatalytic stability. The promoting action is related to the PWA concentration. When the PWA concentration is 0.10 g/L, the promoting action is the best. This is mainly because when the PWA concentration is too high, overfull adsorbed PWA would partially cover the active points of the Pt/C catalyst, leading to the decrease in the electrocatalytic performance of the Pt/C catalyst.
