摘要

Nickel(Ni) and antimony(Sb) co-doped Ti/Ni-Sb-SnO2 electrodes were prepared by pyrolysis coatingmethod and then investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-rayphotoelectron spectroscopy (XPS), linear sweep voltammetry(LSV), electrochemical impedancespectroscopy (EIS) and accelerated service life test. We discussed the changes of oxygen evolutionpotential and charge transfer resistant on the Ti/Ni-Sb-SnO2 electrodes in a physical perspective. Theoxygen evolution potentials improved obviously. Furthermore, the failure mechanisms of the electrodeshave been studied using the EIS and SEM techniques. Our study showed that the deactivation of Ti/NiSb-SnO2 electrode was mainly due to the formation of a passive TiO2 passive interlayer between the Tisubstrate and the coating.
