研究了硝基苯在N-甲基咪唑对甲基苯磺酸([Mim][PhSO3])和1-丁基-3-甲基咪唑六氟磷酸([Bmim][PF6])两种离子液体中的电化学还原反应.循环伏安法测试显示,硝基苯在[Mim][PhSO3]中只出现一个还原峰,是一个受扩散控制的不可逆电化学反应,而在[Bmim][PF6]中出现两对氧化还原峰,表明其还原产物随离子液体性质的不同而异.Electrochemical reduction of nitrobenzene at glassy carbon electrode in different ionic liquids,such as N-methylimidazolium-p-toluene sulfonic acid ([Mim][PhSO3]) and ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF6]) have been investigated by cyclic voltammetry. Experimental results showed that only a cathodic current peak was observed in [Mim][PhSO3],which is a diffusional controlled irreversible reaction. And two pairs of current peaks were obtained in [Bmim][PF6] in the same potential range,indicating showed that the reduction products of nitrobenzene were different in different ionic liquids.
