杂多酸修饰的电极对于甲醇电氧化的促进作用

Promotion Effect of Heteropoly Acids Modified Electrode to Methanol Electrochemical Oxidation

采用杂多酸修饰光滑铂电极 ,研究其对甲醇电催化氧化的作用 ,发现与未修饰光滑铂电极相比 。

Improving the rate of anode reaction in direct methanol fuel cell(DMFC) is the key to increasing the output power of DMFC. In this article, two kinds of heteropolyacids were applied to modify the platinum electrode and their effect on the methanol electrochemical oxidation was studied. The results show that the PWA and SiWA modified platinum electrodes have a promoting effect to the methanol electrochemical oxidation compared with the non-modified platinum electrode.
