▎ 摘  要

NOVELTY - Preparation of graphene aerogel block comprises diluting graphene oxide with predetermined solvent to obtain graphene oxide solution, mixing graphene oxide solution with predetermined reducing agent at 1:0.0001-1:10000 for 1-1000 minutes to obtain mixed graphene oxide mixture, placing graphene oxide mixture in mold, molding at constant temperature and removing excess solvent in graphene oxide mixture. USE - Method of preparing graphene aerogel block (claimed). ADVANTAGE - The aerogel block removes harmful substances e.g. carbon monoxide, tar and nicotine in smoke, has low suction resistance and little nicotine retention and reduces smoking risk of smokers.
