研究了羧酸功能化单壁碳纳米管（SWNTs）膜在玻碳（GC）电极上的电化学行为。一个稳定的电对对应于羧酸基团的氧化还原，这是由XPS和IR实验支持，观察到。电极过程涉及四个电子，而速率决定步骤是一个电子还原。单壁碳纳米管膜修饰电极对多巴胺、肾上腺素和抗坏血酸等生物分子的氧化表现出良好的电催化行为。
The electrochemical behavior of a film of single-wall carbon nanotubes (SWNTs) functionalized with carboxylic acid groups was studied extensively on a glassy carbon (GC) electrode. One stable couple corresponding to the redox of the carboxylic acid group, which was supported by XPS and IR experiments, was observed. The electrode process involved four electrons, while the rate-determining step was a one-electron reduction. The SWNT film-modified electrode showed favorable electrocatalytic behavior toward the oxidation of biomolecules such as dopamine, epinephrine, and ascorbic acid.
