摘 要：用循环伏安测温(CVT)热电化学方法首次研究了Cu2S阳极溶解过程;实测得Cu2S阳极过程的熵变△rSm与根据热力学数据计算所得到的电极反应Cu2S＝CuS+Cu2++2e的熵变值相符;实验的塔费尔(TAFel)斜率B与按迟缓放电机理所导出的TAFel斜率B的理论计算值接近。
Abstract: In this paper Cyclic-Voltammo-Thermometry CVT)technique was first applied tostudying the process of Cu2S anodic dissolution. The entropy change △rS obtained experi-mentally is in agreement with that of the following electrode reaction Cu2S=CuS+Cu2++2eAnd the Tafel’s slope b obtained from CVT experiment indicates that there is the delayeddischarge reaction mechanism of Cu2S anodic dissolution under the conditions studied.
