Outline of Final Research Achievements

Metal-organic frameworks (MOFs) have been recognized as a new candidate for gas and vapor separation. In this study, the structure and the permeation properties of zeolitic imidazolate framework-8 (ZIF-8) based membranes were analyzed. The seeding procedure is the important step for the preparation of MOF based membranes with thin selective layer with fewer defects. We carefully studied the effect of solution concentration, temperature, etc. in the seeding procedure, and analyzed the structure and gas permeation properties. The selective layer of ZIF-8 membranes are polycrystalline, therefore, there exists several permeation path such as ideal molecular sieve permeation path through micro-pore aperture within MOF particle, Knudsen permeation path and viscous flow path.
