Research Abstract |
ZIF-8 membrane was prepared on the porous alumina support by the secondary growth method. The prepared membrane with a thickness of 1-2 um showed the comparable selectivity with Knudsen diffusion in gas permeation tests. From the ethanol/water pervaperation tests, the membrane was slightly water selective. This result unexpected from the hydrophobic nature of ZIF-8 might be caused by high water diffusivity in ZIF-8 resulted by the 'gate-opening' effect.
