“…Thanks to their special structural characteristics including chemical and geometrical flexibility, large specific surface area, and ordered crystalline pores with tunable size and volume, metal‐organic frameworks (MOFs) are broadly believed as excellent candidates for adsorptive separation . In recent years, some MOFs have been applied as the adsorbents for bioalcohol adsorption and purification . For example, zeolitic imidazolate framework‐8 (ZIF‐8), a typical member of the MOF family, can make biobutanol efficiently isolated from its fermentation medium .…”

Core-shell Ag@ZIF-8 nanowires, where single Ag nanowires are coated with uniform zeolitic-imidazolate-framework-8 (ZIF-8) shells, successfully realize renewable adsorptive separation of low concentrations of butanol from an aqueous medium under solar light irradiation by taking advantage of the exceptional adsorption capability of the ZIF-8 shells toward butanol and the unique plasmonic photothermal effect of the Ag nanowire cores. Impressively, the high separation efficiency is maintained as almost unchanged, even after 10 adsorption/desorption cycles.

“…Many other ZIFs such as ZIF‐71, a ZIF built from dcIM (dcIM = 4,5‐dichloroimidazolate) linkers show a similarly strong hydrophobicity. This can be attributed to the combination of the lack of polar centers and the small pore openings . The hydrophobicity of ZIFs can be decreased by installation of polar functionalities in the 5‐position of the imidazolate linkers.…”

Water harvesting from air in passive, adsorption-based devices holds great potential for delivering drinking water to arid regions of the world. This technology requires adsorbents that can be tailored for a maximum working capacity, temperature response, and the relative pressure range in which reversible adsorption occurs. In this respect, metal-organic frameworks (MOFs) are promising, owing to their structural diversity and the precision of their functionalization for adjusting both pore size and hydrophilicity, thereby facilitating the rational design of their water-sorption characteristics. Here, chemical and structural factors crucial for the design of hydrolytically stable MOFs for water adsorption are discussed. Prevalent water adsorption mechanisms in micro- and mesoporous MOFs alongside strategies for fine-tuning of their adsorption behavior by means of reticular chemistry are presented. Finally, an approach for the selection of promising MOFs with respect to water harvesting from air is proposed and design concepts for next-generation MOFs for application in passive adsorption-based water-harvesting devices are outlined.

“…The corresponding peaks at 665 cm -1 (vibration of C-Cl) and 1053 cm -1 (vibration of C-N) matched well with these of the ZIF-71 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 crystals. 16 For comparison, we also prepare the ZIF-71 hollow fiber membrane by the secondary growth method. Only discontinuous membrane can be observed ( Figure S4), indicating that the controlled contra-diffusion process is very beneficial for fabricating integrated ZIF-71 hollow fiber membranes.…”

As a subclass of metal-organic framework materials, zeolitic imidazolate frameworks (ZIFs) have exhibited great potential for numerous applications because of their special three-dimensional structure. Up to now, utilizing ZIF membranes for liquid separations is still limited because it is very difficult to select suitable materials and to fabricate integrated membranes. In this work, a modified contra-diffusion method was carried out to prepare ZIF-71 hollow fiber membranes. The metals Zn(2+) and the organic links imidazole would meet and react on the interface of ceramic hollow fiber through diffusion. The as-prepared ZIF-71 membrane exhibits good performance in separation of ethanol-water mixtures.
