▎ 摘　　要

NOVELTY - Method for preparing graphene oxide and MXene co-doped cellulose-based carbon aerogel, involves (a) blending cellulose and its derivative to biomass-based raw material and graphene to obtain composite aerogel, dissolving graphene oxide in deionized water, ultrasonically dissolving graphene oxide, adding MXene and ultrasonically dissolving graphene oxide, taking 4 ml mixed solution, adding cellulose-based raw material, ultrasonically stirring for uniformly mixing the mixture, adding glucose, uniformly stirring, quickly freezing the prepared mixed solution with liquid nitrogen to obtain graphene oxide/MXene cellulose-based hydrogel, (b) performing freeze drying process on graphene oxide/MXene/cellulose-based hydrogel to obtain graphene oxide/MXene/cellulose-based aerogel, and (c) adding obtained graphene oxide/MXene/cellulose-based aerogel to tubular furnace, and carbonizing under protection of inert gas to obtain black graphene oxide/MXene/cellulose-based carbon aerogel. USE - The aerogel is useful in enrichment of natural products. ADVANTAGE - The method adopts cellulose-based raw materials to prepare graphene oxide and MXene co-doped cellulose-based carbon aerogel, which has excellent adsorption and separation performance.
