摘要：

利用溶胶-凝胶法和电化学聚合制得Ti/nanoTiO₂-PAn复合膜电极，并通过X射线衍射仪（XRD）、扫描电子显微镜（SEM）及循环伏安法（CV）对制备的Ti/nanoTiO₂-PAn复合膜电极的结构、表面形貌和性能进行了表征。以此电极对偶氮染料甲基橙进行了催化降解处理，研究了初始浓度、不同电极等因素对甲基橙电催化氧化降解的影响，结果表明Ti/nanoTiO₂-PAn复合膜电极对甲基橙具有较高的电催化氧化活性，其电催化活性优于Ti/nanoTiO₂电极。

Abstract:

Polymerization of aniline on a nanoTiO₂ complex film electrode was achieved by sol-gel method and electrochemical polymerization technique. XRD，SEM and CV were used to characterize the structure and image of the nanoTiO₂-PAn complex film. The nanoTiO₂-PAn complex film electrode was used to process the electrocatalytic degradation of methyl orange. By using the nano TiO₂-PAn composite film as electrode，effects of initial concentrations，different electrodes and other factors on the electrooxidation degradation of methyl orange were investigated. The Ti/nanoTiO₂-PAn complex film electrode shows a high electrocatalytic oxidation activity in dealing with organic wastewater. The electrocatalytic activity of Ti/nanoTiO₂-PAn complex film electrode is better than that of Ti/nanoTiO₂ electrode.
