The synthesized MOF-177 was found to be six-dimensional shaped channels with an average pore diameter of 1.18 nm. The characterization of synthesized MOF-177 involves the FESEM, powder XRD, FT-IR, TGA/DTG, and BET with nitrogen adsorption. The FESEM images disclosed the distinct crystals with needles type geometrical shape containing large pore with diameter in the range of 20.15 à . The surface area of MOF-177 was found to be 1721 m2/g with CO2 adsorption capacity of 1.03 mmol/g and CO2/CH4 equilibrium selectivity of 3.21 at ambient conditions i.e. 1 atm and 25 °C. MOF-177 found to be in remarkable regeneration ability by sustaining its CO2 adsorption capacity over several adsorption-desorption cycles. Dynamic separation of binary mixture with compositions (CO2:CH4 30:70 and CO2:CH4 70:30) through a fixed bed column revealed that the CH4 pass through the MOF-177 faster than CO2 indicating the higher selectivity for CO2 compared to CH4. Finally, MOF-177 still hold great promise in CO2 separation from natural gas provided it is protected from moisture. © 2019 Elsevier Inc. date: 2019 publisher: Elsevier B.V. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85067830092&doi=10.1016%2fj.micromeso.2019.109569&partnerID=40&md5=539216f9287e701c8a91c0ed2e8be8f9 id_number: 10.1016/j.micromeso.2019.109569 full_text_status: none publication: Microporous and Mesoporous Materials volume: 288 refereed: TRUE issn: 13871811 citation: Ullah, S. and Bustam, M.A. and Assiri, M.A. and Al-Sehemi, A.G. and Sagir, M. and Abdul Kareem, F.A. and Elkhalifah, A.E.I. and Mukhtar, A. and Gonfa, G.
