Porous polymer supported continuous ZIF-8 membranes were prepared via an interfacial synthesis method. Membranes with only one synthesis cycle showed excellent performance in the nanofiltration range.
Zinc-substituted ZIF-67 nanocrystals and polycrystalline membranes for propylene/propane separation.
Continuous ZIF-67 polycrystalline membranes with effective propylene/propane separation performances were successfully fabricated through the incorporation of zinc ions into the ZIF-67 framework. The separation factor increases from 1.4 for the pure ZIF-67 membrane to 50.5 for the 90% zinc-substituted ZIF-67 membrane.
Ionic liquid [Bmim][BF 4 ] and metal organic framework ZIF-8 ZIF-94 nanoparticles were incorporated into polymer Pebax® Renew® 30R51 to obtain highly efficient thin-film nanocomposite membranes, ca. 300 nm thick.
Humidity effects on resistive gas sensors operating at room temperature remain a serious bottleneck. In this work, we introduce sensor based zeolitic imidazolate framework-8/carbon nanotube (ZIF-8/CNT) composite for the detection of ammonia temperature. The was prepared using facile solution method. sensor, basic mechanism charge transfer between molecules and CNTs; meanwhile, ZIF-8 facilitated...
We report a microscopic model of the phonon-adsorption correlations in flexible metal–organic framework materials. analyze mechanism gate opening deformation using notion coupled phonon- and adsorption-induced structural transformation. Using ZIF-8 structure as an example, we perform analysis transformation-related, low-frequency phonon modes framework. On basis structure-related quantities suc...
