| 摘 要： | 采用循环伏安法,在含有0.2mol.L-1苯胺的0.5 mol.L-1的硫酸溶液中,以50mv.s-1的扫描速度,在-0.1~0.9V范围内实现苯胺在碳纳米管-纳米TiO2膜电极上的电化学聚合,得到翠绿色的聚苯胺膜,并用交流阻抗谱对复合膜的电化学性质进行了表征。在该电极上修饰铂,制得铂微粒修饰聚苯胺复合膜电极,研究了其对抗坏血酸的电催化氧化,发现修饰后的电极对抗坏血酸的氧化有很高的催化活性。

| Abstract: | Electrochemical polymerization of aniline on CNT-nano TiO2 film electrode has been achieved in 0.5 mol . L^-1 sulfuric acid including 0.2mol . L^-1 aniline with scanning voltage -0.1V-0.9V at rate 50my . s^-1. Polyaniline film has been characterized by nyquist . Electrode modified with Pt microparticles has been prepared by eleetrodepositing Pt on PANI complex film electrode and its property of electrocatalytic oxidation to ascorbic acid has been observed. The results show the modified electrode has positive electrocatalytic activation to ascorhic acid. |
