Popis: Selective capture of C2H2 and purification of nature gas exert great influence in our modern life and petrochemical industry. In this research, a novel 3D metal organic framework [Cu5L2(H2O)5]∙10DMA constructed by flexible ligand and Cu (II) was obtained via solvothermal. The adsorption property of this material was studied. The maximum adsorption capacity for N2 is 425.3 cm3 g−1 under the 77 K and 1 atm, which corresponds to the specific surface areas of 1560 m2 g−1. At 278 K, its absorption capacity towards C2H2, CO2 and CH4 are 132.7, 90.2 and 25.8 cm3 g−1, respectively. The high ability to capture acetylene makes it possible to be used to separate and purify gas mixtures C2H2/CH4 and CO2/CH4.
