In this study, a facile, fast, and cost-effective method for the synthesis of high-quality reduced graphene oxide sheets is reported by a microwave-assisted chemical reduction using hydroiodic acid/acetic acid as reducing agent. Exposure of graphene oxide (GO) with microwave irradiation (4 and 7h) was found to be more rapid and sustainable reduction as compared to that of the conventional chemical reduction process (48h). Formation of high-quality microwave-assisted reduced GO (mrGO) was ensured by means of electron microscopies, Raman, and infrared spectroscope studies. Furthermore, the antibacterial activity was evaluated for the mrGO, which showed good inhibitory effect against both Gram positive and Gram negative bacteria.
