| 摘 要： | 用循环伏安法研究了儿茶素在玻碳电极(GCE)和多壁碳纳米管修饰玻碳电极(MWCNT/GCE)上的电化学行为,探讨了电极反应机理。结果表明:MWCNT/GCE对儿茶素具有显著的电催化作用,儿茶素在MWCNT/GCE上的氧化还原峰电位差比在GCE上明显减小,且峰电流显著增加。电极反应为2电子、2质子转移的准可逆反应过程。

| Abstract: | The electrochemical behaviors of catechin on the GCE and MWCNT/GCE were studied by cyclic votammetry,and the mechanism of electrode reaction was discussed.The results indicate that MWCNT/GCE has obvious electrocatalytic effect on catechin,and the catechin redox peak potential difference is smaller on the MWCNT/GCE than that on the bare GCE,but peak current greatly increases.The electrode reaction of catechin is two-electron and two-proton quasi reversible process. |
