| 摘 要： | 报道了一种多壁纳米碳管修饰电极的制备方法并表征了它的电化学特性.经酸处理后的纳米碳管表面有碳酸根基团存在,当它被修饰到电极表面时会产生一对氧化还原峰.该修饰电极对发生在它表面上的电极反应具有明显的促进作用;对生物物质多巴胺的氧化还原具有稳定的电催化作用.

| Abstract: | The preparation of multiwalled carbon nanotube modified electrode is reported and the electrochemical behavior of electrode is characterized. There are carboxylic acid groups and carboxylate groups on the surface of mixed acid-treated carbon nanotube. A couple redox peaks is observed when the surface of glassy carbon electrode was modified by multiwalled carbon nanotube to form a modified electrode. The electrode obviously promotes electron transfer rate occurring at the electrode surface and shows stable electrocatalytic behavior to the oxidation dopamine. |
