▎ 摘　　要

NOVELTY - Preparing graphene powder comprises dispersing graphene oxide in water at normal temperature to form a graphene oxide aqueous dispersion, adding reducing sugar to the dispersion according to a mixing ratio, uniformly dispersing by ultrasound, disposing the mixed solution, stirring the reaction for 1-5 hours under light conditions, cooling the product, centrifuging the product, washing, spray-drying, drying and grinding. USE - The method is useful for preparing graphene powder.
