为了提高电解海水防污用钌系金属氧化物阳极的析氯电流效率、强化电解寿命、耐正反电流交替电解性能及抗Mn2+污染性能,采用热分解法制备了不同配比的RuO2-IrO2-SnO2和PtO2-RuO2-IrO2-SnO2氧化物涂层阳极,通过对2种阳极的形貌、强化电解寿命、耐正反电流交替电解性能、析氯电流效率及耐Mn2+污染性能的对比,研究了Pt组元对阳极性能的影响.结果表明:RuO2-IrO2-SnO2氧化物阳极具有较高的初始析氯电流效率和较长的强化电解寿命,表现出优良的抗Mn2污染性能；通过添加适量Pt组元制备的PtO2-RuO2-IrO2-SnO2氧化物阳极除具备上述优点外,还具有优异的耐正反电流交替电解性能.
