Heterometallic metal-organic framework and Carbon dioxide adsorbents comprising the same

摘要

The present invention relates to a metal-organic framework represented by the following [Formula 1] and a carbon dioxide adsorbent comprising the same: [Formula 1] [M x M' 2-x (dobpdc)(SOL1) y (SOL2) 2-y ] A In Formula 1, M and M' are different from each other, and each is a divalent metal selected from the group consisting of Mg, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn, The dobpdc is 4,4'-dihydroxy-[1,1'-biphenyl-3,3'-dicarboxylate], The SOL1 and SOL2 are different from each other and each is a non-diamine-based solvent selected from methanol, ethanol, dimethylformamide, tetrahydrofuran, and water (H 2 O), or ethylenediamine (en), dimethylethylene It is a diamine-based solvent selected from diamine (mmen), piperazine (ppz), N,N-dimethylethylenediamine, N-ethylethylenediamine and N-isopropylethylenediamine, A is at least one organic solvent selected from ethanol, methanol, dimethylformamide (DMF), diethylformamide, water and acetonitrile; wherein x is a real number greater than 0 and less than 2, and y is a real number greater than 0 and less than or equal to 2.
