| 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 voltammetryIt is showed that with the increasing of the concentration of nitrobenzene in RMimBF4，α decreases，while temperature make reversed effect at the same nitrobenzene concentrationα 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 |
