| Abstract: Herein, a novel metal-organic framework {[Co(DTBDA)]2·DMF·MeOH}n (FJI-H37) was prepared by solvothermal reaction of cobalt nitrate with ligand 5,5'-di(1H-1,2,4-triazol-1-yl)-(1,1'-biphenyl)-2,2'-dicarboxylic acid (H2DTBDA). FJI-H37 not only has 0.69 nm of micropores for gas adsorption but also possesses good thermal stability and organic solvent tolerance. The gas adsorption tests show that FJI-H37 can not only selectively adsorb C2H2 from a C2H2/CO2 (50:50, V/V) mixture with a relatively high adsorption selectivity of 4.2, but also selectively capture CO2 from a CO2/N2 (15:85, V/V) and CO2/CH4 (50:50, V/V) mixture; which can be further confirmed by the dynamic fixedbed breakthrough experiments.
