NOVELTY - Preparation of graphene oxide by water-soluble initiator involves using the graphite powder as a raw material, adding the raw material to a three-necked flask, adding appropriate amount of a solvent to the flask, stirring the mixture to uniformly disperse the graphite powder in the solvent, adding the initiator, reacting the contents under the action of stirring and ultrasonication, and obtaining graphene by centrifugation. USE - Preparation of graphene oxide by water-soluble initiator. ADVANTAGE - The whole process is simple, efficient, environmentally-friendly, and free from strong acid and metal ion pollution.
