摘要
利用碳包覆铜纳米粒子修饰的玻碳电极作为工作电极,用循环伏安法测试对硝基苯酚在碱性水溶液中的电化学行为.通过对不同浓度溶液和以不同速度扫描,并与裸玻碳电极扫描结果比较,表明碳包覆铜纳米粒子具有良好的电化学催化性能,显著提高了对硝基苯酚的反应活性.
A glass carbon electrode modified with carbon-encapsulated copper nanoparticles was prepared as working electrode.The electrochemical behavior of p-nitrophenol was tested by cyclic voltammetry in alkaline solution.Compared with the bare glassy carbon electrode,the modified electrode exhibited excellent electrocatalytic activity for the degradation of p-nitrophenol,and increased peak current.The influencing factors,such as scanning rate,solution concentration and so on,were discussed.
