Facile and effective oxidation of graphite using sodium metaperiodate

摘要

A novel effective and facile oxidation process of graphite using sodium metaperiodate is reported. The formed graphene oxide is confirmed by XRD, XPS and C-13 NMR MAS spectra. AFM images show the size of the layer to be around 0.9-1.1 nm and the carbon-oxygen ratio is calculated as 2.09. The new method of synthesis can be referred as non-metallic oxidation of graphite, which is easy to remove the impurities with no evolution of toxic gases. (C) 2017 Elsevier B.V. All rights reserved.
