▎ 摘　　要

NOVELTY - A spongy light graphene aerogel is prepared by placing not greater than 10 mg/ml graphene oxide colloidal solution into 0.01-0.1 wt.% surfactant, dissolving, using high speed stirring device to obtain graphene oxide foam suspension, and putting into liquid nitrogen for freezing. USE - Method for preparing spongy light graphene aerogel (claimed). ADVANTAGE - The aerogel has stable structure, has good property and excellent characteristics, reduces system surface tension solution, and increases ratio surface area, adsorption performance for dye and organic solvent material. The method is simple, and has low cost.
