摘要

采用循环伏安法研究了离子液体RMimBF4中硝基苯在微铂电极上电还原动力学特性参数——传递系数α的变化规律。研究结果表明，离子液体中，硝基苯电还原过程的第2个电子转移反应是速度控制步骤。该反应的传递系数α随硝基苯浓度增加而减小;相同浓度时，温度升高，α迅速增大。在离子液体EMimBF4-水-硝基苯体系中，相同硝基苯浓度下，随水含量增加，α先减小，后增大。不同离子液体中，α的变化规律为：EMimBF4＞〖JP〗BMimBF4＞HMimBF4。

Abstract

he transfer coefficient α of nitrobenzene electrochemical reduction in RMimBF4 was investigated by cyclic voltammetryIt is showed that with the increasing of the concentration of nitrobenzene in RMimBF4，α decreases，while temperature make reversed effect at the same nitrobenzene concentrationα decreases in the order EMimBF4＞BMimBF4＞HMimBF4，at equal nitrobenzene concentration，the value of α is reduced in EMimBF4-H2O at low water concentration and has reversed effect at high water concentration
