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.

Abstract

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 voltammogram,double layer capacitances and accelerated life of anode coatings had a tendency 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.
