▎ 摘  要

NOVELTY - A graphene microsheet dispersion is prepared. The graphene microsheet in dispersion is pore-forming etched. Porous graphene microsheet is prepared. Porous graphene microsheet, fatty acid metal composite coating agent and dopant are mixed, to obtain oil-phase viscous graphene precursor. The oil-phase viscous graphene precursor is heat treated. The heat treated product is pickled, washed, solid-liquid separated and dried, to obtain heteroatom-doped graphene multistage mesoporous carbon material. USE - Preparation of heteroatom-doped graphene multistage mesoporous carbon material (claimed). ADVANTAGE - The method enables preparation of heteroatom-doped graphene multistage mesoporous carbon material with high yield and low energy consumption by economical and simple method.
