Synthesis of graphene oxide from industrial waste
This paper investigates a synthesis of graphene oxide (GO) from industrial waste via leaching and modified Hummers method. In leaching process, most of the impurities were effectively removed by dissolving into 6 M HCl at 70 °C for 210 mins to produce 92.28 % purity graphite residue. Subsequently, G...
