摘要

循环伏安法研究葡萄糖在离子液体[EMI]BF4中于碳纳米管/纳米TiO2膜载Pt(CNT/nanoTiO2-Pt)复合膜电极上的电催化氧化.结果表明,CNT/nanoTiO2-Pt电极对葡萄糖氧化具有高催化活性,氧化电位为-0.46V;在组成为离子液体与水的体积比为3∶1的电解液中,葡萄糖的氧化效果最好.电极反应过程受浓差极化控制.

Abstract

Using ionic liquid [EMI]BF4 as the electrolyte,the electrocatalytic oxidation of glucose on carbon nanotubes/nanocrystlline TiO2 film loaded on Pt (CNT/nanoTiO2-Pt) complex film electrode was investigated by cyclic voltammetry. The results found that the CNT/nanoTiO2-Pt complex electrode had high catalytic activity to the electrochemical oxidation of glucose in ionic liquids and the oxidation potential was -0.46 V. The best effect of glucose oxidation was obtained with the volume ratio of ionic liquid to water being 3∶1. The process of electrodic reaction process was concentration polarization controlled.
