%X Under the scope of this study, graphene sheets were produced with different graphite precursors by electrochemical exfoliation technique as an environmentally friendly approach. Pure graphite and pencil core with different grade were used as a precursor material (working electrode). A Pt wire and Ag/AgCl were used as counter and reference electrode, respectively. Electrodes were immersed into H2SO4 electrolyte solution. The resultant electrochemically exfoliated graphene sheets (EGS) were dispersed in N,N-dimethylformamide (DMF) by sonication at low power for 10 min. Structural analysis of as obtained EGS were performed by Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy, and X-Ray Diffraction (XRD) spectroscopy. Microscopic structure of the pre- and post-production of graphite and as obtained graphene sheets were investigated by Field Emission Scanning Electron Microscopy (FE-SEM). The purity of the graphene sheets was identified qualitatively by Electron Diffraction spectroscopy (EDS).
