摘　　要：应用溶胶凝胶法制备了不同钌锡摩尔比氧化物阳极涂层.SEM,EDX,强化电解寿命,循环伏安和电化学阻抗等测试表明,钌锡摩尔比对阳极涂层的表面形貌以及电化学性能有很大影响.随着钌含量的增加涂层的强化电解寿命呈先增加后降低变化,析氯电位呈先降低后增加;电流效率呈先增加后降低,与其对应的循环伏安电量以及双电层电容值亦呈先增加后减小变化.The anode coatings of Ru-Ir-Sn oxide with different Ru/Sn ratios were prepared by sol-gel method. The influences of Ru/Sn ratio on properties of anode coatings were studied by scanning electron microscope （SEM）, energy dispersive X-ray detector（ EDX）, X-ray diffraction（XRD）. The potential of chlorine evolution, current efficiency, accelerated life, cyclic vohammetry and electrochemical impedance spectroscopy （EIS） tests were carried out. The results showed that there was an obvious effect of Ru/Sn ratio on the morphology of the coatings. The cyclic vohammogram, double layer capacitances and accelerated life of anode coatings had a tend- ency to fall down firstly then increased as the Ru% increased, the current effency and potential of chlorine evolution had a tendency to decreased firstly then increased as the Ru% increased.
