摘　　要：对ＩｒＯ２／Ｔｉ、ＳｎＩｒＯ２／Ｔｉ、引进阳极３种涂层阳极的组织、结构、电化学性能、抗钝化性能进行了研究，并着重分析了Ｓｎ元素在涂层中所起的作用，结果表明添加Ｓｎ的ＩｒＯ２／Ｔｉ阳极具备优异的电催化及抗钝化性能的结论，可作为硫酸中使用的电极材料．The surface morphology, phase component, electrochemical behavior and durability of three types of anodes including IrO 2/Ti, Sn IrO 2/Ti were investigated in comparison with one anode coating imported. The action of Sn element in coating was analyzed. It was shown that Sn IrO 2/Ti anode had the best electrocatalytical performance and durability. It colud be chosen to be an electrode material in sulfuric acid.
