▎ 摘　　要

NOVELTY - Preparing three-dimensional hierarchical porous carbon material compounded by graphene/mesoporous carbon/ZIF derived carbon comprises (i) adding phenol source and aldehyde source into the graphene oxide dispersion liquid, then adding surfactant, obtaining reaction liquid A, under the condition of heating and sealing, carrying out polymerization reaction to obtain hydrogel, freezing and drying to obtain phenolic resin coated graphene oxide aerogel, (ii) adding the zinc nitrate hexahydrate and the phenolic reinforcement coated graphene dioxide aerogels into the methanol, uniformly mixing, adding methanolin solution dissolved with methyl imidazole to obtain reaction liquid B, self-assembling at room temperature to obtain graphene oxide/phenolic resin /ZIF-8 composite material, (iii) carbonizing graphene oxide/phenolic Resin/ZIF-8 composite material under the inert atmosphere, washing and drying by hydrochloric acid, and activating. USE - The method is useful for preparing three-dimensional hierarchical porous carbon material compounded by graphene/mesoporous carbon/ZIF derived carbon. ADVANTAGE - The graphene/mesoporous carbon/ZIF derived carbon composite three-dimensional graded porous carbon material has high specific surface area and high stability, and excellent electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene/mesoporous carbon/ZIF derived carbon composite three-dimensional graded porous carbon material.
