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