Investigating the effect of graphite electrodes structures on the synthesized graphene using electrochemistry method

In this study, a simple and efficient approach is reported to product graphene using electrochemicalexfoliation of graphite electrodes, in acidic solutions. The electrolyte concentration, applied voltages, electrodesdistance and preparation time were taken as control parameters to optimize the produced graphene structures. Theoptimized graphene sample was prepared in a H2SO4 (0.5 M) at a bias of +10 V. The interlayer spaces, crystallitesize and the average number of layers were determined by XRD. Surface morphology, layer thickness andcharacteristics of obtained samples were investigated by Scanning Electron Microscopy (SEM), Atomic ForceMicroscopy (AFM), and FTIR. The obtained results confirmed the graphene structures.
