对RuTiSn、RuTiIrSnCo、IrTiTa和Pt/Ti电极在1mol/LH2SO4中的强化电解失效行为进行了研究.结果表明:IrTiTa阳极的强化电解寿命最高,Pt/Ti电极次之,RuTiSn电极最低.氧化物层的溶解消耗、剥落以及在活性层和基体间有钝化膜生成是氧化物阳极失效的几种主要原因,每种电极失效均是多种因素共同作用的结果,但不同的阳极有着不同的导致失活的主导因素.针对氧化物阳极的失效原因,提出了氧化物阳极性能改进的可能途径.
The enhanced electrolytic failure behavior of RuTiSn, RuTiIrSnCo, IrTiTa and Pt / Ti electrodes in 1 mol / LH 2 SO 4 was studied. The results show that IrTiTa anode has the highest electrolysis life, followed by Pt / Ti electrode and RuTiSn electrode. Dissolution of the oxide layer, exfoliation and formation of a passive film between the active layer and the substrate are the main causes of the oxide anode failure. The failure of each electrode is the result of a combination of factors, but different anodes have Different leading factors leading to inactivation. Aiming at the failure reason of oxide anode, some possible ways to improve the performance of oxide anode are proposed.
