Electrochemical Behavior of Novel Ti/IrOx−Sb2O5−SnO2 Anodes

摘要: There are growing interests in anodes for oxygen evolution because of the importance this reaction many electrochemical processes such as water electrolysis, electroplating, electrosynthesis, metal electrowinning, and electroflotation. Ternary IrOx−Sb2O5−SnO2 has been shown to be among best elecytrocatalysts evolution. Its high stability relatively low cost will make it more attractive than IrOx other electrocatalytic materials. In paper, open-circuit potential, voltammetric behavior, mechanism, kinetics coated titanium were studied. It was found that potential could change significantly during initial period time probably hydration coating film. Cyclic voltammograms obtained on Ti/IrOx−Sb2O5−SnO2 somewhat different from those anodes. Apparent cathodic peaks Ir(III)/Ir(IV) Ir(IV)/Ir(V) observed. However, corresponding anodic peaks...
