A highly permeable and selective zeolitic imidazolate framework ZIF-95 membrane for H2/CO2 separation

Abstract

Making use of the preferred adsorption affinity and capacity to CO2 as well as the highly porous structure with huge cavities of 2.4 nm, a highly permeable and selective ZIF-95 molecular sieve membrane was developed for the separation of H2 from CO2. © 2012 The Royal Society of Chemistry.
