▎ 摘  要

NOVELTY - Preparation of mesoporous graphene-based carbon aerogel involves taking resorcinol and formaldehyde as reactants, sodium carbonate as catalyst and graphene oxide dispersion as additive, performing sol process to obtain resorcinol-formaldehyde-graphene oxide hydrogel, drying at room temperature under normal pressure, carbonizing and activating carbon dioxide and potassium hydroxide. USE - The method is useful for preparation of mesoporous graphene-based carbon aerogel, which is useful for lithium-ion capacitor electrode material. ADVANTAGE - The method enables preparation of graphene-based carbon aerogel with high specific surface area and mesoporous ratio and excellent rate performance. The graphene-based carbon aerogel provides high specific capacity and performance to the lithium-ion capacitor electrode material.
