Abstract:
Mass production of high-quality graphene sheets is essential for their practical application in different fields. Herein, we reported a simple, green, and cost-effective approach to synthesizing mass-production graphene flakes via
electrochemical exfoliation of pencil cores in neutral aqueous electrolytes. Pencil graphite cores were applied as anode
and cathode electrodes and exposed to the electrolyte solution at a different voltage. Several parameters were examined and optimized, including pencil grade (2,4,6,8 B), applied voltage (10, 15, 20, 30 V), different inorganic electrolytes ((NH4)2SO4, Na2SO4, NaNO3, NaCl, and CH3COONa), and the concentration of electrolytes. The optimal condition was chosen by considering the mass of produced graphene, the conductivity of graphene solution, and the IR spectra. The
IR spectrum for the obtained graphene was similar to the commercial graphene and different from those for graphite and graphene oxide. The optimal conditions were as follow: pencil grade: 6B; applied voltage: 10V; electrolyte type:
Na2SO4; electrolyte concentration: 0.1M. Under these conditions, the production yield was >95% within 3h and 9 min.
Our present results are promising for scaled-up preparation and further commercialization of graphene in a low-cost and environmentally friendly way, especially in low-income countries
