Zusammenfassung:The invention discloses a zinc-based metal organic framework material Zn-DPT-PTOBA as well as preparation and application of the zinc-based metal organic framework material Zn-DPT-PTOBA. The chemical formula of the Zn-DPT-PTOBA is Zn3 (DPT) 2 (PTOBA) 2, the PTOBA is 4-(5-p-methyl-1, 3, 4-oxadiazole-2-yl) benzoic acid, and the DPT is 3, 5-bis (1H-pyrazole-4-yl)-4H-1, 2, 4-triazole-4-amine. The Zn-DPT-PTOBA can be obtained by putting a metal zinc salt, a ligand H2DPT, a ligand HPTOBA and a mixed solvent into a closed reaction container according to a ratio and carrying out solvothermal reaction. The metal organic framework material Zn-DPT-PTOBA has a PtS type topological network structure and is excellent in thermal stability and chemical stability, the initial adsorption heat of the metal organic framework material Zn-DPT-PTOBA to carbon dioxide exceeds 80 kJ/mol, CO2 can be efficiently and selectively adsorbed, and the theoretical selectivity of an ideal adsorption solution for CO2 in flue gas (CO2/N2 = 15/85
