| 摘 要： | 制备了多壁碳纳米管/磷钼酸复合膜修饰电极,用交流阻抗法对该电极进行了表征,用循环伏安法研究了该修饰电极对过氧化氢的电催化特性,并对其稳定性进行了测定。实验结果表明：电极表面已修饰了致密的碳纳米管磷钼酸膜;在过氧化氢浓度为3.0～13.0 mmol/L范围内,催化电流与过氧化氢的浓度呈现良好的线性关系;修饰电极具有良好的稳定性。

| Abstract: | GC/MWNTs/PMo12O403-modified electrode was prepared and characterized by the electrochemical impedance spectroscopy measurements.It was found that the electrode was modified by carbon nanotubes/phosphomolybdic acid.The electrochemical characteristics of the modified electrode were studied by using cyclic voltammetry.There was a good linear relationship between the peak currents and the concentrations of H2O2 in the range of 3.0~13.0 mmol/L.The modified electrode had good stability. |
