The electroreduction performance of p-nitrotoluene in ionic liquid EMBF4 was studied by means of cyclic voltammetry.Experimental results showed that p-nitrotoluene could be reducted in EMBF4.By the curve of cyclic voltammetry,the first and second electroreduction peak potential were shifted to the negative direction with the increasing concentration of p-nitrotoluene,the responding electroreduction peak current were also increased,with the increasing concentration of water,the first electroreduction peak po...
