Herein, we present a new robust Fe(iii) based PCP (labelled MIL-178(Fe)) built up from chains of corner sharing Fe octahedra interconnected by 1, 2, 4-benzene tricarboxylic acid, delimiting one dimensional narrow pore channels (pore diameter < 4.5 angstrom) decorated with polar groups (mu(2)-OH and -CO2H functions). These structural and chemical features are suitable for the selective adsorption of CO2. MIL-178(Fe) was synthesized following a simple and green protocol in water under near ambient conditions using non-toxic reactants, allowing the production of sub-micrometer sized MIL-178(Fe) particles in a large amount (30 g). As shown by single-gas isotherms and CO2/N-2 co-adsorption experiments as well as molecular simulations, this material exhibits a moderate CO2 capacity at low pressure but a high CO2/N-2 selectivity. This is fully consistent with the presence of mu(2)-OH groups acting as CO2 adsorption sites, as revealed from both molecular simulations and in situ PXRD experiments. Finally, the good compatibility of this MOF with the elastomer block copolymer Pebax (R)-3533 allowed the processing of homogeneous and defect-free mixed matrix membranes with a MIL-178(Fe) loading of up to 25 wt% that outperformed pure Pebax (R)-3533 membranes for CO2/N-2 separation. info:eu-repo/grantAgreement/EC/FP7/608490/EU/Energy efficient MOF-based Mixed Matrix Membranes for CO2 Capture/M4CO2 info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 11.9 2022 CHEMISTRY, PHYSICAL 24 / 161 = 0.149 2022 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 32 / 343 = 0.093 2022 Q1 T1 ENERGY & FUELS 11 / 119 = 0.092 2022 Q1 T1 3.156 2022 Chemistry (miscellaneous) 2022 Q1 Renewable Energy, Sustainability and the Environment 2022 Q1 Materials Science (miscellaneous) 2022 Q1 22.0 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Wahiduzzaman, Mohammad Zhao, Heng Hasan, Md Rafiul Steenhaut, Timothy Saad, Ali Marrot, Jérôme Normand, Périne Greneche, Jean-Marc Heymans, Nicolas De Weireld, Guy Tissot, Antoine Shepard, William Filinchuk, Yaroslav Hermans, Sophie Carn, Florent Manlankowska, Magdalena Téllez, Carlos Universidad de Zaragoza (orcid)0000-0002-4954-1188 Coronas, Joaquín Universidad de Zaragoza (orcid)0000-0003-1512-4500 Maurin, Guillaume Steunou, Nathalie Serre, Christian 5005 555 Universidad de Zaragoza Dpto.
