Abstract
The present invention relates to a graphene oxide material, a halogenated graphene material, preparation methods therefor, and an electrolysis system. A method for producing a graphene oxide material in an electrolysis system comprises the following steps: applying a voltage between a working electrode and a counter electrode, and exfoliating graphite and/or amorphous carbon under the action of electrolysis so as to generate the graphene oxide material, wherein before applying the voltage and/or in the process of applying the voltage, light irradiation is performed on the electrolysis system.
