1 Introduction High-permeance separation membranes are highly desirable for reducing membrane area and cost in critical applications such as hydrogen (H2) and carbon dioxide (CO2) separation.[1-5] Conventional gas separation material, i.e., polymers, has been developed for this separation.[6] However, the state-of-the-art polymeric membranes yield low H2 permeance and modest H2/CO2 selectivity.[7, 8] Polycrystalline metal–organic framework (MOF) films hosting ordered, uniform Å-scale pores...
