Current polymer membrane materials applied for gas separation are not good enough to satisfy the permeability-selectivity requirements: there is a trade-off between both parameters that limits its application, even though gas seperation membranes are much more energy efficient than other gas separation technologies. MOF (metal-organic framework) based membranes (both mixed matrix membranes and continuous membranes) could constitute the definitive separation systems to afford this challenge task. MOFs are porous crystalline organic/inorganic materials with pore apertures ranging from 0.3 nm to 1.7 nm, i.e. appropriate to produce molecular sieving and preferential absorption effects, promoting the separation of, for instance, precombustion (H2/CO2) and postcombustion (CO2/N2) mixtures.
