Abstract :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 insert ignore into journalissuearticles values(working electrode);. A Pt wire and Ag/AgCl were used as counter and reference electrode, respectively. Electrodes were immersed into H 2 SO 4 electrolyte solution. The resultant electrochemically exfoliated graphene sheets insert ignore into journalissuearticles values(EGS); were dispersed in N,N-dimethylformamide insert ignore into journalissuearticles values(DMF); by sonication at low power for 10 min. Structural analysis of as obtained EGS were performed by Fourier Transform Infrared insert ignore into journalissuearticles values(FTIR); spectroscopy, Raman spectroscopy, and X-Ray Diffraction insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(FE-SEM);. The purity of the graphene sheets was identified qualitatively by Electron Diffraction spectroscopy insert ignore into journalissuearticles values(EDS);.
