摘要： hrough bio-inspired polydopamine modification of the ceramic support surface, dense and reproducible zeolitic imidazolate framework (ZIF) membranes have been developed for the first time for seawater desalination by pervaporation. Demonstrated by both experimental and simulation studies, the developed ZIF membranes show high desalination performances attributing to the small pore size of the ZIF membranes, which is exactly in between the size of water molecules and hydrated ions. The ZIF membranes show a high stability in seawater. At 25, 50, 75 and 100 °C, the water fluxes through the ZIF-8 membrane are 5.8, 8.1, 10.8, and 13.5 kg/(m2·h), re- spectively, with a high ion rejection of over 99.8%, which is promising for seawater desalination by ionic sieving.

摘要： A superhydrophobic zeolitic imidazolate framework (ZIF-90) with high steam stability is prepared through post-functionalization via an amine condensation reaction. The developed superhydrophobic ZIF-90 is highly promising as an effective and reusable adsorbent for bio-alcohol recovery.

摘要： With global appeal to green and efficient utilization of energies, metal-organic frameworks based mixed matrix membranes are standing out in applications such as gas and liquid separation because of the integration of size/shape selectivity of MOFs with p

摘要： Through layer-by-layer [LBL] deposition of a graphene oxide [GO] suspension on a semicontinuous ZIF-8 layer, we have developed a novel bicontinuous ZIF-8@GO membrane. Since only the gaps between the ZIF-8 crystals are sealed by the GO layer due to capilla
