Today, due to the momentary release of carbon dioxide and increasing global heat, solutions that prevent this greenhouse gas into atmosphere are very important. In work, a nanoporous sorbent with 3D framework chemical formula [Ca1.5(FDC)1.5(DMF)] (MUT-13) (FDC2–= furan-2,5-dicarboxylate, DMF= N,N-dimethylformamide) was prepared in different synthetic routes. Single crystal MUT-13 identified by X-ray crystallographic analysis other physicochemical analyses. Then, help GCMC, performance simulated adsorption various gases (CO2, H2, C2H2, CH4, N2) under temperature pressure conditions. Also, potential separating from binary mixtures (CO2/CH4, CO2/N2, CO2/H2 CO2/C2H2) investigated. The results indicated sorption structure has high capacity adsorb (6.2 mmol.g–1) acetylene (5.5 molecules environmental It also shows separation greater than 5000 2000 for mixture CO2:H2 at low pressures, respectively. This good adsorbing compared MOF-based adsorbents can be related surface its pores decorated heteroatom ligand presence unsaturated metal centers structure.

Reduction of atmospheric carbon dioxide, which is one the main components affecting global warming, and hydrogen storage as a renewable energy source by effective sorbents are considered to be vital challenges. In this work, nanoporous pillared-layered metal–organic framework [Zn2(TDC)2(DABCO)]·(DMF)4 (1) (TDC2– = thiophene-2,5-dicarboxylate, DABCO 1,4-diazabicyclo[2.2.2]octane, DMF N,N-dimethylformamide) sorbent was synthesized several methods, its structure determined single-crystal X-ray analysis. Then, physicochemical characteristics were investigated using set analyses. The potential 1 in capturing nitrogen, hydrogen, dioxide gases at different temperatures showed that product made sonochemical method has higher capacity for adsorption due larger surface area compared products other methods. maximum 1.97 mmol·g–1 273 K bar, displaying good MOF performance low pressures. Also, than well-known MOFs, such ZIF-8, MOF-508, PCN-13, under similar conditions. Moreover, isosteric heat calculated coverage, revealing interaction nature between gas molecules resulting dependence sorption on temperature. better adsorbing CO2 H2 some reported MOFs may related pores decorated with hetero atoms sulfur.
