Microwave‐assisted Synthesis, Characterization of Reduced Graphene Oxide, and Its Antibacterial Activity

Abstract

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 7 h) was found to be more rapid and sustainable reduction as compared to that of the conventional chemical reduction process (48 h). 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.
