A high-metallic cluster nuclei constructed - organic framework material and method

A thermally stable metal-organic framework material is high, which is the formula [NH2 (CH3) 2] [Ni2 (μ3-OH) 3 (bptc) 0.5 (H2O) 2] · H2O, where: bptc 3,3 ' , 5,5'-biphenyl tetracarboxylic acid ion, NH2 (CH3) 2 dimethylamine cation; the preparation method of 3,3 ', 5,5'-biphenyl tetracarboxylic acid, nickel acetate tetrahydrate , lithium hydroxide monohydrate and a concentrated nitric acid was added N, N- dimethylformamide (DMF) and distilled water, heated at 170 ℃ 72 hours to obtain a green bulk crystal hexagonal, washed and dried to give the title product; the materials can be used to capture CO2. Advantage of the present invention are: high product yield, the metal-organic framework material prepared having high thermal stability, and has high CO2 adsorption capacity and adsorption enthalpy greater.
