A facile and scalable bottom-up method is used to synthesize a microporous jungle-gym-like metal-organic framework [Cu-2(ndc)(2)(dabco)](n) in the morphologies of nanocubes and nanosheets. The obtained MOFs are blended with polybenzimidazole yielding a series of mixed matrix membranes (MMMs), which are evaluated for their performance in pre-combustion CO2 capture (H-2/CO2 separation). Pure gas permeation tests indicate that MMMs with partially oriented nanosheet MOFs possess the largest improvement compared with neat polymers, with the overall H-2/CO2 separation performance exceeding the 2008 polymer upper bound.
