摘要 在钛板上电沉积TiO2纳米管,并通过层层组装方式制备了Ti/TNTs-Sb-SnO2-rGO电极。用扫描电镜(SEM)、X射线衍射(XRD)、X射线光电子能谱(XPS)以及电化学等方法对电极形貌、微观结构和性能进行了表征。实验结果表明,该电极具有高的析氧电位(2.1V)和良好的导电性能。在亚甲基蓝(MB)模拟染料废水的电氧化降解实验中,该电极能够有效去除有机污染物,降解1h,去除率为97%,降解过程符合一级动力学方程,反应速率常数为0.057min-1,降解机理为间接电化学氧化过程。电极的实验室加速寿命为9h,折合工业寿命为1.6a,表明该电极具有较长的使用寿命。

Abstract: Ti/TNTs-Sb-SnO2-rGO electrode was prepared using layer by layer coating of “Sb-Sn” mixture solution and graphene oxide on Ti/TNTs electrode,TiO2 nanotube was firstly electrodeposited on Ti plate.The morphology,microstructure and performance of prepared electrodes were characterized by SEM,XRD,XPS and electrochemical method.It shown that Ti/TNTs-Sb-SnO2-rGO exhibited high oxygen evolution potential(2.1V) and outstanding electrical conductivity.Electrocatalytic oxidation degradation of methylene blue (MB,simulated dye wastewater) was used to evaluate the efficiency of Ti/TNTs-Sb-SnO2-rGO.MB was effectively degraded within 60min and the removal rate reached 97%.The degradation process followed a pseudo first order kinetics with a rate constant (k) value of 0.057min-1.The degradation mechanism was proved to be indirect electrochemical oxidation process.The electrode acceleration life was 9h (the real industrial life was 1.6 years),indicating that the electrode had good stability and long service life.
