摘　　要：采用热分解法,在钛基体上制备了具有不同中间层及不同金属元素配比的Ru–Ir–Sn–Ti氧化物涂层阳极,通过扫描电子显微镜、X射线衍射、极化曲线、强化电解寿命和循环伏安曲线,研究了该氧化物涂层阳极的物理性能和电化学性能,并与Ru–Ir–Ti氧化物涂层阳极进行了比较。结果表明,以IrO2·SnO2为中间层的Ru–Ir–Sn–Ti(摩尔比16∶16∶4∶64)氧化物涂层阳极有较好的电催化性能,其强化寿命达432h。Ru-Ir-Sn-Ti oxide-coated anodes with various intermediate layers and metal proportions were prepared on Ti substrate by thermal decomposition. The physical and electrochemical properties of the oxide-coated anodes were studied by SEM, XRD, polarization curve, accelerated life testing and cyclic voltammetry and compared with Ru-Ir-Ti oxide-coated anode. The results showed that the Ru-Ir-Sn-Ti oxide-coated anode with a molar proportion of 16：16：4：64 has good electrocatalytic capability with an accelerated life of 432 h.
