Abstract

Graphene is a two-dimensional allotrope of carbon, in which carbon atoms are arranged in a hexagonal structure. All carbon atoms in graphene are sp2 hybridized due to which three atoms are bonded to neighboring atoms and one electron is unbounded. Here, we have demonstrated a facile and low-cost technique to synthesize the graphene oxide and reduced graphene oxide from readily available battery graphite by means of an electrochemical method using liquid electrolyte. The graphite in the battery electrode has been expanded using acid for effective exfoliation. This is used to increase the interlayer spacing of graphite causes the van der Waals forces to cease. Graphene oxide and reduced graphene oxide (reduction using ascorbic acid) have been synthesized using this technique. The optical microscope image has shown few layer flakes and X-ray powder diffraction (XRD) demonstrated the reduction of oxygen content. The proposed setup is cheap and environmentally benign in nature.
