Well matched: Submicrometer-sized metal–organic framework (MOF) crystals (ZIF-90) were synthesized by a nonsolvent-induced crystallization technique and incorporated in mixed-matrix gas-separation membranes. ZIF-90/6FDA-DAM membranes (empty pink circle; beyond the upper bound for polymer membranes) show unprecedented high performance CO2/CH4 separation MOF-based membrane. The key is combination of highly selective MOF permeable polymer.
Propylene/propane separation is one of the most challenging separations, currently achieved by energy-intensive cryogenic distillation. Despite great potential for energy-efficient membrane-based no commercial membranes are available due to limitations current polymeric materials. Zeolitic imidazolate framework, ZIF-8, with effective aperture size ∼4.0 Å, has been shown be very promising propylene/propane separation. extensive research on ZIF-8 membranes, only a few reported have displayed...
Molecular layer-by-layer (mLbL) assembled thin-film composite membranes fabricated by alternating deposition of reactive monomers on porous supports exhibit both improved salt rejection and enhanced water flux compared to traditional reverse osmosis prepared interfacial polymerization. Additionally, the well-controlled structures achieved mLbL further lead antifouling performance. As a service our authors readers, this journal provides supporting information supplied authors. Such materials...
ZIF-67, a Co-substituted ZIF-8 structure, is investigated as candidate for the industrially highly demanding propylene/propane separation, with use of computational techniques first time. A new force field ZIF-67 framework based on density functional theory calculations reported along recently developed ZIF-8. The validated through comparison structural data from literature. Molecular dynamics simulations are showing dramatic increase corrected diffusivities ratio when compared to ZIF-8,...
Independent control of the extrinsic and intrinsic properties polyamide (PA) selective layer is essential for designing thin-film composite (TFC) membranes with performance characteristics required water purification applications besides seawater desalination. Current commercial TFC fabricated via well-established interfacial polymerization (IP) approach yield materials that are far from ideal because their thickness, surface roughness, polymer chemistry, network structure cannot be...
The facile tuning of the gate size and chemical functionalization zeolitic imidazolate framework-8 (ZIF-8) were achieved by postsynthetic modification with 3-amino-1,2,4-triazole. resulting amine functionalized ZIF-8 particles enabled CO<sub>2</sub> selective adsorption further modifications.
The sharkskin-mimetic, patterned TFC RO membranes exhibited superior biofouling resistance compared to conventional and simple membranes.
Metal-organic frameworks with high aspect ratios have the potential to yield high-performance gas separation membranes. We demonstrate scalable synthesis of high–aspect ratio zeolitic imidazolate framework (ZIF)–8 nanoplates via a direct template conversion method in which ratio–layered Zn hydroxide sheets [Zn5(NO3)2(OH)8] were used as sacrificial precursor. Successful phase occurs result collaboration low stability and delayed delivery 2-methylimidazole weakly interacting solvents,...
Separation membranes with high performance can potentially be made by incorporating zeolites (or other nanoporous molecular sieves) in polymeric materials. However, the fabrication of technologically viable has been hampered poor adhesion between inorganic crystals and polymer inadequate dispersion particles. We report a facile, high-yield, inexpensive solvothermal deposition process to prepare roughened Mg(OH)(2) nanostructures on zeolite (MFI) crystal surfaces controlled manner. The...
Der Schlüssel für die ungewöhnlich hohe Leistung der auf Metall-organischen Gerüsten (MOFs) beruhenden ZIF-90/6FDA-DAM Membran (leerer rosafarbener Kreis im Diagramm, jenseits oberen Grenze Polymermembranen) bei CO2/CH4-Trennung ist Kombination eines hoch selektiven MOF in Form submikrometergroßer Kristalle mit einem durchlässigen Polymer als Gastrennungsmembran. Die ZIF-90-Kristalle wurden durch eine nicht das Lösungsmittel induzierte Kristallisation erhalten. Detailed facts of importance...

The dual-layer slot coating technique can fabricate a sub-10 nm ultrathin, highly selective membrane outperforming commercial reverse osmosis membranes.
We report for the first time that ZIF-8 crystals undergo an Ostwald-ripening-like process without degradation in presence of a ligand vapor. The ripening is dependent on defect density crystals: more defective amenable to ripening. was adapted synthesize ultra-thin membranes by vapor-phase secondary growth.
