▎ 摘　　要

NOVELTY - A graphene-protein composite airgel is prepared by adding graphite oxide, protein, and reducing agent in aqueous solution, sonicating to obtain homogeneous solution, heating in water bath to obtain graphene-protein composite hydrogel, and drying. USE - Preparation of graphene-protein composite airgel (claimed). ADVANTAGE - Graphene-protein composite airgel is 3-dimensional, porous, and flexible, has good pollutant adsorption capacity and low cost, and reduces toxicity. DESCRIPTION OF DRAWING(S) - The drawing shows an adsorption curve of methyl orange and tetracycline using graphene-protein composite airgel with different specific gravity. (Drawing includes non-English language text).
