| 摘 要： | 在含有0.2 mol·L-1苯胺的0.5 mol·L-1 H2SO4溶液中;采用循环伏安法（CV）;以扫描速度50 mV·s-1;扫描电位为-0.1～0.9 V;在碳纳米管/纳米TiO2（CNT/nanoTiO2）膜电极上实现了苯胺的电化学聚合;通过CV法和电化学阻抗谱（EIS）并结合电子扫描显微镜和红外谱图对制备的碳纳米管/纳米TiO2-聚苯胺（CNT/nanoTiO2-PAn）复合膜电极的电化学性质和结构进行了表征;同时研究了复合膜电极对抗坏血酸（AH2）的电催化性能;发现该复合膜电极对抗坏血酸的氧化具有较高的电催化活性。

| Abstract: | Polymerization of aniline on carbon nanotube/nanocrystalline TiO2（CNT/nanoTiO2）film electrode performed in 0.5 mol·L-1 sulfuric acid including 0.2 mol·L-1 aniline with scanning voltage -0.1V—0.9V at scanning rate 50 mV·s-1.
The electrochemical properties and structure of carbon nanotube/nanocrystalline TiO2-polyaniline（CNT/nanoTiO2-PAn）complex film were characterized with cyclic voltammetry（CV）;electrochemical impedance spectra（EIS）;SEM and IR spectra.In addition;electrocatalytic performance of the complex film electrode was investigated for oxidation of ascorbic acid（AH2）.It was found that the complex film electrode exhibited excellent catalytic activity toward the electrooxidation of ascorbic acid. |
