The use of mixed matrix membranes (MMMs) to facilitate the production biofuels has attracted significant research interest in field renewable energy. In this study, pervaporation separation butanol from aqueous solutions was studied using a series MMMs, including zeolitic imidazolate frameworks (ZIF-8)-polydimethylsiloxane (PDMS) and zinc oxide-PDMS membranes. Although several studies have repo...

Metal-organic frameworks (MOFs) were supported on polymer membrane substrates for the fabrication of composite polymer membranes based on unmodified and modified polymer of intrinsic microporosity (PIM-1). Layers of two different MOFs, zeolitic imidazolate framework-8 (ZIF-8) and Copper benzene tricarboxylate ((HKUST-1), were grown onto neat PIM-1, amide surface-modified PIM-1 and hexamethylene...

A series of five zeolitic imidazolate frameworks (ZIFs) have been synthesized using zinc(II) acetate and five different 4,5-functionalized imidazole units, namely ZIF-25, -71, -93, -96, and -97. These 3-D porous frameworks have the same underlying topology (RHO) with Brunauer-Emmet-Teller surface areas ranging from 564 to 1110 m(2)/g. The only variation in structure arises from the functional g...

The elastic properties of a zeolitic metal-azolate framework, Zn(mtz)2 (MAF-7, mtz− = 3methyl-1,2,4-triazolate), have been examined from the view point of the first principles calculations and experiments. Our results demonstrate that the three independent elastic constants of MAF-7 are about 5.0–73.3% higher than those of ZIF-8, though they are isomorphic. The electron-donating effect of the n...

Abstract Reduced graphene oxide (rGO) combined with zeolitic imidazolate framework (ZIF), i.e., rGO-ZIF incorporated polyetherimide (PEI) electrospun nanofiber, was produced using the electrospinning technique. The nanofibers had high porosity enhanced conductivity. ionic conductivity, porosity, morphology, and diameter of nanofiber were optimized by manipulating weight percentage PEI in soluti...

The landscape of possible polymorphs for some metal–organic frameworks (MOFs) can pose a challenge controlling the outcome their syntheses. Demonstrated here is use template to control in vapor-assisted formation zeolitic imidazolate framework (ZIF) powders and thin films. Introducing small amount either ethanol or dimethylformamide vapor during reaction between ZnO 4,5-dichloroimidazole result...
