Simulation and synthesis of graphene oxide from expanded graphite

Аннотация

Expanded graphite oxide and multilayered graphene oxide have been synthesized. The processes of thermal expansion of intercalated graphite and oxidation of graphene have been simulated. Thermal expansion of intercalated graphite and its oxidation into graphite oxide have been studied by a set of physico-chemical methods. Quantum-chemical simulation has revealed that the edge atoms of the graphene layers appearing during thermal expansion are the most active in the reactions of graphene oxidation.
