▎ 摘　　要

NOVELTY - Preparing cellulose/reduced graphene oxide porous gas gel, comprises mixing the cellulose and solvent uniformly to obtain cellulose solution, ultrasonically dispersing the reduced graphene oxide by dimethyl sulfoxide, adding the cellulose solution, stirring and mixing, then pouring the stirred and mixed solution into a mold, forming adhesive in water, freezing and drying to obtain final product. USE - The cellulose/reduced graphene oxide porous gas gel is useful in the field of dye adsorption (claimed), and as a green adsorbent of wastewater dyes. ADVANTAGE - The cellulose/reduced graphene oxide porous gas gel achieves excellent adsorption of methylene blue (MB) in the dye solution with MB, excellent cyclic adsorption performance, and is environmentally-friendly biomass material.
