摘要
用滴涂法制备了杂多酸修饰多壁碳纳米管载铂催化剂(Pt/C N Ts-H PA),研究了它在硫酸中的电化学行为以及对甲醇的电催化氧化。实验结果表明,与Pt/C N Ts修饰电极相比,Pt/C N Ts-H PA修饰电极对甲醇电催化氧化速率明显增加,且对甲醇的催化氧化是扩散控制的电化学反应过程,该修饰电极具有良好的稳定性。
Pt/CNTs-HPA modified electrode was prepared by dropcoating method.Its electrochemical behaviors in H2SO4 solution and electrocatalytic oxidation of methanol were studied.The results show that Pt/CNTs-HPA modified electrode has promoting effects on the methanol electrochemical oxidation compared with the Pt/CNTs modified electrode.The electrocatalytic oxidation of methanol is a diffusion-controlled process.The modified electrode has good stability.
