▎ 摘　　要

NOVELTY - A porous graphene is prepared by providing graphene sheet having thickness of 0.5-2 nm and lateral dimension of 1-30 microns, and uniformly distributed pores having size of 10-500 nm on the surface of the graphene sheet. USE - Porous graphene is used in adsorption, catalysis and gas separation applications and supercapacitor. ADVANTAGE - The porous graphene is prepared by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of porous graphene, which involves dissolving chitosan in aqueous acetic acid, obtaining aqueous solution of chitosan acetate, adding graphene, uniformly stirring, placing the obtained mixture in ultrasonic cleaner, ultrasonically treating at 10-75 degrees C and 420-600 W, centrifuging the resultant product, and obtaining graphene material having porous structure.
