采用热分解法制备了SnO2-Sb2O3-RuO2/Ti电极，并将其用于苋菜红模拟染料废水处理。实验表明电极制备的最佳条件为：烧结温度为500℃，涂层数为6层，n(Sn):n(Sb):n(Ru)=10:1:1。通过XRD、SEM和CV对电极表面形貌、表面微观结构和电化学性能进行测试，结果表明：SnO2-Sb2O3-RuO2/Ti电极表面晶体为四方金红石结构且晶型单一；表面晶粒细小平整，晶粒间结合紧密；具有较好的电催化活性和较长的强化试验寿命。
SnO2-Sb2O3-RuO2/Ti thin film electrode was prepared by thermal decomposition method in this paper. It is used to treat Amaranth dye simulate wastewater. The decolourization efficiency of amaranth is studied and the optimal operating conditions of the electrode are ascertained as follows: the sintered temperature is 500℃, the optimal coating layer is 6, the coating oxides proportion is n(Sn):n(Sb):n(Ru)=10:1:1. The surface morphology, microstructure, electrochemical and accelerated test shows that the surface of the SnO2-Sb2O3-RuO2/Ti electrode has the quartet rutile structure, even crystal size, good adhesion, low porosity and high catalytic-activity and long service-life .
