▎ 摘　　要

NOVELTY - Graphene oxide reduction comprises adding solution of halogen in organic solvent to 0.1-5 mg/ml aqueous dispersion of graphene oxide and ultrasonically dispersing; adding hydrohalic acid and refluxing at 60-100 degrees C for 1-4 hours; and hot-filtering, washing, and drying. USE - Method for reducing graphene oxide (claimed). ADVANTAGE - The method is environment-friendly and simple; has short reaction time, good reducing effect (carbon/oxygen (C/O) of 19.7-21.9), low energy consumption and low pollution; and can easily realize continuous graphene oxide reduction.
