High hydrogen selectivity and thermal stability are displayed by a membrane of zeolitic imidazolate ZIF‐22 grown on porous ceramic supports by using 3‐aminopropyltriethoxysilane (APTES) as covalent linker (see picture). At 323 K, H 2 /CO 2 selectivity of 7.2 and H 2 permeance of 1.6×10 −7 mol m −2 s −1 Pa −1 were achieved.
