▎ 摘  要

NOVELTY - Preparing metal organic framework/graphene aerogel composite material, comprises (i) dissolving the ionic liquid in metal salt solution, stirring fully to make evenly mixing to obtain metal salt-ionic liquid solution, (ii) placing the graphene aerogel in the metal salt-ionic liquid solution, allowing the solution to stand for a period of time, and fully diffusing the metal salt-ionic liquid solution into the graphene aerogel to obtain solid-liquid mixture, (iii) adding the alkaline ligand salt solution into the solid-liquid mixture and fully stirring, and then obtaining the precipitate of the lower layer by centrifuging, and (iv) adding the precipitate into the solvent, stirring well and allowing to stand for a period of time, then filtering to obtain a solid product, heating and drying to obtain final product. USE - The method is useful for preparing metal organic framework/graphene aerogel composite material. ADVANTAGE - The metal organic framework/graphene aerogel composite material: promotes the nucleation and growth of metal organic framework by adding ionic liquid; provides the ligand through the alkaline ligand salt solution, which is conducive to the fully contacting and reacting between the organic ligand and the metal salt; and realizes the adjustment of the loading amount of the metal organic framework in the composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for metal organic framework/graphene aerogel composite material, obtained by above mentioned method.
