SnO_2-Sb_2O_3-RuO_2/Ti电极制备及其性能研究
|
摘要
采用热分解法制备了SnO_2-Sb_2O_3-RuO_2/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:SnO_2-Sb_2O_3-RuO_2/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。
SnO_2-Sb_2O_3-RuO_2/Ti thin film electrode was prepared by a thermal decomposition method and it was used to treat Amaranth dye simulated wastewater. The decolourization efficiency of amaranth was studied. Results show that the optimal operating conditions of the electrode are as follows: the sintered temperature 500 °C, the optimal coating layer 6, and the coating oxides proportion n(Sn):n(Sb):n(Ru)=10:1:1. The surface morphology, microstructure, electrochemical and accelerated test indicate that the surface of the SnO_2-Sb_2O_3-RuO_2/Ti electrode has the quartet rutile structure with single crystal form, good adhesion, low porosity and high catalytic-activity and a long service-life.
