摘　　要：制备了稀土多金属氧酸盐/多壁碳纳米管修饰Pt电极(POM-CNTs/Pt),研究了它对乙醇的电催化氧化。实验结果表明,与CNTs/Pt修饰电极相比,POM-CNTs/Pt修饰电极对乙醇电催化氧化速率明显增加,且对乙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。POM-CNTs/Pt modified electrode is prepared and Its electrocatalytic oxidation of ethanol is studied. The results show that POM-CNTs/Pt modified electrode has promoting effect on the ethanol electrochemical oxidation compared with the CNTs/Pt modified electrode. Electrocatalytic oxidation of ethanol is the diffusion-controlled process. The modified electrode has good stability.
