Zeolitic imidazolate frameworks (ZIFs), a subclass of metal organic frameworks, are built of tetrahedral metal ions bridged by imidazolates. They have permanent porosity and relatively high thermal and chemical stability, which make them attractive candidates for many industrial applications. In recent years, significant progress has been made in developing ZIFs into membranes and thin films fo...
The objective of this work is to develop a new class of nanocomposite ultrafiltration (UF) membranes with excellent solute rejection rate and superior water flux using zeolitic imidazolate framework-8 (ZIF-8) and multi-walled carbon nanotubes (MWCNTs). The effect of ZIF-8 and MWCNTs loadings on the properties of polyvinyldifluoride (PVDF)-based membrane were investigated by introducing respecti...
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...
