摘　　要：用电化学和Ｘ射线衍射方法研究了氧化物涂层成分对热分解法制备的ＩｒＯ２（５）ＴｉＯ２（６０）Ｃｏ３Ｏ４（ｘ）ＲｕＯ２（３５—ｘ）／Ｔｉ阳极材料析氯速率的影响．ｘ值为０－１３ｍ／ｏ时，氧化物涂层为单相金红石型固溶体，阳极析氯速率随ｘ值增加，ｘ值大于１３ｍ／ｏ时，涂层中出现尖晶石Ｃｏ３Ｏ４第二相，析氯速率随ｘ值下降．The effect of composition of oxide coating on the chlorine evolution rate of IrO2(5)TiO2(60)Co3O4(x) RuO2(35-x) / Ti anode prepared by thermal decomposition method was studied by x-ray diffraction and electrochemical techniques. The coating consisted of single phase of rutile- type solid solution and chorine evolution rate icreased with x as x in 0- 13 m/ o range, second phase of spinel Co3O4 emerged and chlorine evolution rate decreased with x as x was more than 13m / o.
