Abstract

A rapid preparation method of graphene oxide (GO), a promising key material for future technology, has been developed. The most common method for synthesizing GO, namely Hummers' method (oxidation with KMnO4 and NaNO3 in concentrated H2SO4), requires long reaction time and large amounts of reagents. We have found that the microwave irradiation of natural graphite flake before oxidation step improved the efficiency of the oxidation process. This facile method provides a greater amount of GO as compared to the original Hummers' method. Our rapid synthetic method would contribute to large-scale production of GO. As an application, we used GO as a functional support material of metal nanoparticles.
