Sodium hydride's ability to convert graphene oxide (GO) to reduced graphene oxide (RGO) and deprotonate methanol to the methoxy ion is applied to the preparation of a stable RGO dispersion in methanol. The process is extremely fast with high yield and produces RGO with a high density of sp2 carbon atoms. RGO sheets (see image) are characterized electrically and spectroscopically.
