Abstract

In this paper, four types of titanium based metal oxides electrodes were prepared by thermal decomposition method: Ti/SnO₂+Sb₂O₃, Ti/SnO₂+Sb₂O₃/SnO₂+IrO₂, Ti/SnO₂+Sb₂O₃/SnO₂+RuO₂, Ti/SnO₂+Sb₂O₃/SnO₂+CeO₂. The XRD results show that CeO₂ in Ti/SnO₂+Sb₂O₃/SnO₂+CeO₂ displayed a good crystal structure, and there was no significant oxygen evolution reaction occurred after electrolytic oxidation. Compared with the other three electrodes, the Ce-doped electrode exhibited the best electro-catalytic activity: the degradation of the simulated wastewater with high concentration (500 mg·L^-1) was 180 mg·L^-1, and the degradation efficiency was up to 64%.
