摘要
以甲苯 乙醇混合体系作溶剂 ,用循环伏安法和交流阻抗法研究了二茂铁在铂电极上的电化学行为 ,进而测试了H2 O2 存在时二茂铁的循环伏安曲线。结果表明 ,混合溶剂中溶液电阻和二茂铁在铂电极上的电化学反应电阻均随甲苯含量的增加而增大 ,二茂铁正离子能与H2 O2 发生均相化学反应 ,其电极反应机理为包含随后转化步骤的催化反应过程 ,即EC历程。
The electrochemical behavior of ferrocene in the absence and presence of hydrogen peroxide in toluene-ethanol mixed solutions were investigated at a platinum electrode by cyclic voltammetry and AC impedance measurements. The results show that increasing toluene in the solution mixture leads to increase of both solution resistance and electrochemical reaction resistance of ferrocene at the Pt electrode. Ferricinium ion could react with hydrogen peroxide in the liquid phase. The electrode process is considered to be followed by catalytic EC(electron transfer-chemical reaction) mechanism.
