用电沉积法制备了Ti/SnO2+ S2Ox/PbO2耐酸阳极,采用交流阻抗法测定了电极的导电性,利用加速寿命实验测定了电极的加速使用寿命,同时引入循环伏安新方法定量考察不同sb掺杂物质的量分数对电极表面分形维数的影响,并且讨论了电极在酸性溶液中的析氧电催化性能.结果表明,sb掺杂物质的量分数在0.02和0.10时Ti/SnO2+ Sb2Ox/PbO2电极的分形维数较高,表明电极表面粗糙程度较大,析氧电催化性能较好,是优良的高析氧电位下的阳极材料,适用于阳极氧化获得产品的电极过程.Sb掺杂物质的量分数为0.06时Ti/SnO2+ Sb2Ox/PbO2电极的导电性最好,加速使用寿命达到89 h.因此.Ti/SnO2+ Sb2Ox/PbO2电极是酸性溶液中较好的阳极材料.
