▎ 摘  要

NOVELTY - Graphene is mixed with sulfuric acid and potassium permanganate, and reacted at 30-40 degrees C for 1-3 hours, and further heated to 95-100 degrees C for 10-20 minutes. Distilled water is added to the reaction mixture, and hydrogen peroxide is further added and reacted. 5 Wt.% hydrochloric acid solution is added to the mixture and centrifuged. The graphene oxide obtained is washed with acetone and vacuum dried at 100-1200 degrees C to obtain graphene nano-sheet. USE - Manufacture of graphene nano-sheet used for carbon dioxide adsorbent. ADVANTAGE - The graphene nano-sheet has excellent carbon dioxide adsorption effect.
