为解决传统铅银合金存在的铅污染和钛基PbO:(DSA)基体易钝化、使用寿命短等问题,以不锈钢为基体,用稀土Ce改性,制备了PbO2-CeO2电极。分析了PbO2的形成机理,通过析氧曲线、Tafel曲线、EDS能谱及扫描电镜考察了温度、电流密度、稀土ce等对电极性能的影响及所制备电极的元素分布及表面形貌。结果表明:最佳制备工艺为190g/LPb(N03)2,15g/L Cu(N03)2,O.5g/LNaF,30g/LCe02,pH值为2~3,机械搅拌,温度70℃,电流密度10~20mA/cm2,时间30min;所制备的镀层平整、均匀,电化学性能优良,镀层中CeO2,质量分数约为4%~6%;PbO2CeO2电极析氧电位1500mV左右,节能性能明显优于传统惰性阳极。
