▎ 摘  要

NOVELTY - Producing composite pore organic/inorganic carbon body by directly impregnating the metal-organic framework precursor in the reduced graphene oxide airgel comprises (I) preparing a reduced graphene oxide airgel by adding an aqueous solution of graphene oxide in an autoclave and performing a hydrothermal reaction, (II) preparing a metal-organic framework precursor by dissolving ferric chloride and terephthalic acid in dimethylformamide, (III) preparing a reduced graphene oxide airgel-MIL precursor by injecting the metal-organic framework precursor prepared by step (II) into reduced graphene oxide airgel, the reduced graphene oxide airgel-MIL precursor mixture is homogenized and (IV) preparing metal-intermetallic laminated (MIL)/reduced graphene oxide airgel composite by putting the reduced graphene oxide airgel-MIL precursor prepared by the above three steps into an autoclave and performing a solvothermal reaction. USE - The method is useful for producing composite pore organic/inorganic carbon body. ADVANTAGE - The method can increase the degree of dispersion of the metal-organic framework nanoparticles; has improves fluidity, thermal conductivity, and adsorption/desorption performance of gas molecules, and can improves stability of metal-organic framework nanoparticles by carbon support under high temperature and high pressure conditions. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for composite pore organic/inorganic carbon body comprising impregnating metal-organic framework precursor in the reduced graphene oxide airgel and the metal-organic framework is dispersed in airgel pores.
