▎ 摘　　要

NOVELTY - The preparation method of black phosphorus graphene nanosheet involves adding black phosphorus crystal and organic solvent to an agitation barrel, uniformly mixing, stirring the mixture and then rotating using a high-speed rotary cutter, processing the mixture under argon gas atmosphere and then dispersing, centrifuging the mixture and then filtering, and washing. USE - The method is useful for preparation of black phosphorus graphene nanosheet (claimed). ADVANTAGE - The method enables economical preparation of black phosphorus graphene nanosheet with high yield.
