▎ 摘　　要

NOVELTY - Preparing nitrogen-doped reduced graphene oxide- based aerogel with a highly regularized structure, comprises: mixing the graphene, nitrogen containing compound and reducing agent, then performing gelation reaction to obtain hydrogel precursor; drying the hydrogel precursor sequentially, carbonizing and cooling. USE - The method is useful for preparing nitrogen-doped reduced graphene oxide- based aerogel with a highly regularized structure, used in adsorption material. ADVANTAGE - The method has simple technique, low cost, mild condition. The aerogel has gel-like bionic structure, high regularity degree, faster adsorption, better oil-water separation selectivity, which is good for industrial expanding production and popularization and use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for nitrogen-doped reduced graphene oxide- based aerogel with a highly regularized structure.
