| Outline of Final Research Achievements |
Metal-organic frameworks (MOFs) have attracted tremendous attentions as new materials for separation membranes. In this study, we developed uniquely micro-structured MOF-based molecular sieve membranes by a counter-diffusion method using porous α-alumina hollow substrate. We successively applied the counter-diffusion method for the preparation of zeolitic imidazolate frameworks-8 (ZIF-8) based membranes. Permeation properties were studied using the single-component gas permeation properties, and ideal propylene/propane separation factor of up to 135 was achieved. We clarified the contribution of diffusive separation for propylene/propane with ZIF-8 membranes based on the characterization of diffusion and solution properties from the membrane permeation measurements. The preparation, structural characteristics, and gas permeation properties of the ZIF-8 membranes prepared by the counter-diffusion method are thoroughly studied.
