▎ 摘　　要

NOVELTY - A porous graphene airgel is prepared by taking graphite oxide, dispersing in deionized water, formulating to 1-6 mg/mL graphene oxide solution, sonicating, magnetic stirring, thoroughly dispersing, dropping reducing agent, magnetic stirring, pouring into container, sealing, incubating at 90-120 degrees C for 6-18 hours to obtain graphene hydrogel, immersing in deionized water, removing graphene hydrogel, placing in clean container, rapidly freezing at less than or equal to - 60 degrees C, and lyophilizing. USE - Method for preparing porous graphene airgel (claimed).
