摘　　要：采用刷涂热分解法制备了Ti/Sb–SnO2电极,采用扫描电子显微镜(SEM)、能量色散谱(EDS)、X射线衍射仪(XRD)和电化学测量技术(包括线性扫描伏安曲线、循环伏安曲线和计时电位曲线)对所制备电极的微观形貌、元素组成、物相组成和电化学性能进行了分析。结果表明:Ti基体表面为蜂窝状结构,而Ti/Sb–SnO2电极表面形成了SnO2晶胞,电极表面活性层的催化性能明显提高。A Ti/Sb-SnO2 electrode was prepared by thermal decomposition. The micro-morphology, elemental composition, phase structure and electrochemical properties of the electrode were analyzed by scanning electron microscopy （SEM）, energy-dispersive spectroscopy （EDS）, X-ray diffraction （XRD） and electrochemical measurement technologies including linear sweep voltammetry, cyclic voltammetry and chronopotentiometry. It was found that Ti electrode has a honeycomb-like structure and SnO2 crystal cells are formed on the surface of Ti/Sb-SnO2 electrode, which evidently improves the catalytic property of the electrode.
