where MB molecules exhibited two redox peaks at 0.48 V and 0.34 V, respectively, in cyclic voltammogram (CV).
The features of redox couples indicated the dimerizationofMBmolecules.Inthissimplepreparationtechnique,alessamountofsampleloadingwas required, and the method displayed high efficiency toward decolorization of MB dye. This report indicates the possibility for improving the quality of wastewater discharged from textile and other industries.
