NOVELTY - A metal organic frame material comprises a porous structure, and is doped with lanthanide element and graphene. USE - Metal organic frame material (claimed). ADVANTAGE - The metal organic frame material has high specific surface area, high carbon dioxide adsorption capacity, improved adsorption property of the adsorbent material, and adjusts the doping amounts of the lanthanide and graphene to satisfy the different requirements for the adsorption of different gases. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of metal organic frame material, which involves mixing N,N-dimethylformamide, anhydrous ethanol and deionized water as solution, adding europium nitrate, terephthalic acid and graphene oxide to the solution to obtain mixture, dispersing the mixture, stirring, hydro-thermally reacting, filtering the mixture, and drying.
