Zeolitic Imidazolate Framework-8 Membrane for H2/CO2 Separation: Experimental and Modeling

In this work, ZIF-8 membrane synthesized through solvent evaporation secondary seeded growth was tested for single gas permeation and binary gases separation of H2 and CO2. Subsequently, a modified mathematical modeling combining the effects of membrane and support layers was applied to represent th...
