Abstract

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.
