中文摘要：

以铜盘电极为工作电极, 采用循环伏安和原位红外反射光谱技术研究了硝基甲烷在离子液体1-正丁基-3-甲基咪唑四氟硼酸盐（BMImBF4）中的电还原行为, 讨论了温度和扫描速度等因素对其电还原行为的影响. 研究结果表明, 硝基甲烷在离子液体BMImBF4中的还原反应是受扩散控制的不可逆过程, 其还原产物为亚硝基甲烷二聚体.

英文摘要：

The electrochemical behavior of nitromethane were studied by cyclic voltammetry and in situ FTIR technique in the room temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluorobrate（BMImBF4） on a copper disk electrode. The influences of temperature and scan rate on the electrochemical characteristics of nitromethane were also investigated. Results show that the electroreduction of nitromethane in BMImBF4 is an irreversible process, which is controlled by diffusion. Finally nitromethane is reduced into trans-dimer of nitrosomethane in BMImBF4.
