The prepared membranes, with loadings up to 55 wt%, have been characterized through several techniques (XRD, SEM, FTIR, TGA, 13C NMR and XPS) and the changes in the morphology of the fillers upon combination with PBI, as well as in the chemical environment of their main atoms (interactions between the linker of the filler and the benzyl rings of the polymeric bIm units) are discussed. All the membranes have been tested at temperatures ranging between 70 and 200 °C to study their H2/CO2 separation performance. The integration of both types of MOF in the polymeric phase improves not only the hydrogen permeability but also the selectivity in comparison with the pure polymer in all cases. H2 permeability increases due to a better diffusion of the penetrants, while CO2 adsorption on the MOF and solution in the polymer decreases. The best result obtained corresponds to the membrane with 55 wt% loading of ZIF-11, with 495 Barrer of H2 permeability and a H2/CO2 selectivity of 7.0. 000148547 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000148547 590__ $$a8.867$$b2016 000148547 591__ $$aCHEMISTRY, PHYSICAL$$b15 / 144 = 0.104$$c2016$$dQ1$$eT1 000148547 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b19 / 273 = 0.07$$c2016$$dQ1$$eT1 000148547 591__ $$aENERGY & FUELS$$b4 / 89 = 0.045$$c2016$$dQ1$$eT1 000148547 592__ $$a3.075$$b2016 000148547 593__ $$aChemistry (miscellaneous)$$c2016$$dQ1 000148547 593__ $$aRenewable Energy, Sustainability and the Environment$$c2016$$dQ1 000148547 593__ $$aMaterials Science (miscellaneous)$$c2016$$dQ1 000148547 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000148547 700__ $$0(orcid)0000-0002-9934-1707$$aZornoza, B. 000148547 700__ $$0(orcid)0000-0002-4954-1188$$aTéllez, C.$$uUniversidad de Zaragoza 000148547 700__ $$0(orcid)0000-0003-1512-4500$$aCoronas, J.$$uUniversidad de Zaragoza 000148547 7102_ $$15005$$2555$$aUniversidad de Zaragoza$$bDpto.
