The chemical production of graphene as well as its controlled wet chemical modification is a challenge for synthetic chemists. Furthermore, the characterization of reaction products requires sophisticated analytical methods. In this Review we first describe the structure of graphene and graphene oxide and then outline the most important synthetic methods that are used for the production of these carbon-based nanomaterials. We summarize the state-of-the-art for their chemical functionalization by noncovalent and covalent approaches. We put special emphasis on the differentiation of the terms graphite, graphene, graphite oxide, and graphene oxide. An improved fundamental knowledge of the structure and the chemical properties of graphene and graphene oxide is an important prerequisite for the development of practical applications.

High-efficient Synthesis of Graphene Oxide Based on Improved Hummers Method (2016, background): “Our improvement works can be ascribed to following factors: (1) the intercalation and preoxidation of flake graphite is enhanced by using K2FeO4 as a stronger oxidant25,35 which partly replaces KMnO4 at extended low-temperature stage; (2) the secondary feeding of KMnO4 prevents it from fast decompos”
Progress in the functional modification of graphene/graphene oxide: a review (2020, neutral): “Accordingly, in recent years, other models have been proposed, such as the dynamic structure model (DSM) 40,41 and binary structure model.”
Production and processing of graphene and related materials (2020, background): “Chemical bulk functionalization of graphene using graphite as starting material has gained significant interest since it allows (i) the generation of exfoliated graphite sheets in large quantities compared to other exfoliation techniques [375, 377, 1230], (ii) access to solution-processable graphene”
