Adhesion between fillers and a polymeric matrix is an essential characteristic for mixed-matrix membranes molecular separation to avoid defects cavities that would decrease selectivity. We demonstrate here how solution rheology can be excellent tool identity polymer–filler pairs with strong interaction. The investigated system was polytriazole without hydroxyl functionalization (PTA-OH PTA) ZIF...

• Defect-free ZIF-8/GO/PIM-1 thin-film nanocomposite (TFN) membranes were fabricated. 2D ZIF/GO was produced by in situ growth of ZIF-8 on GO sheets as a continuous, uniform and thin layer. ZIF-8/GO composite results high dispersity compatibility ZG within PIM-1. PIM-1 infiltration into PVDF substrate avoided water pre-impregnation. TFN display PSI (228 kg m −2 h −1 ). In this work, film super-...

Highly sensitive semiconductor gas sensors hold great potential for applications in trace detection. Reliable detection of ppb-level NO2 is crucial environmental monitoring, which however still remains a challenge. In this work, we adopted one-pot encapsulation strategy synthesizing indium-doped ZnO porous hollow cages. In(acac)3 was selected as the indium source due to its molecular diameter b...

A series of fluorescein-encapsulated zeolitic imidazolate framework-8 (fluorescein@ZIF-8) luminescent nanoparticles with a scalable guest loading has been fabricated and characterized. The successful encapsulation the organic dye (fluorescein) is supported by both experimental evidence theoretical simulations. measured optical band gap found to be comparable computed values hypothetical guest-h...

A metal-organic framework, Zn-[2-methylimidazolate] frameworks (ZIF-8), was used as adsorbent material to remove different concentrations of oxytetracycline (OTC) antibiotic in a fixed-bed column. The OTC was studied at concentrations of 10, 25 and 40 mg L(-1). At 40 mg L(-1), the breakthrough point was reached after approximately 10 minutes, while at 10 and 25 mg L(-1) this point was reached i...

The development of sorbent materials with high carbon dioxide (CO2) selectivity is vital importance to minimize the impact global warming by separating and capturing this major greenhouse gas. In work, for first time five ammonium-based ionic liquids (ILs) were impregnated into metal-organic framework (MOF) ZIF-8 gas sorption applications. Characterization results showed that produced [email pr...

The aim of this work was to develop hybrid TiO2/ZIF-8 photocatalysts and test their activity for the removal agricultural pollutants in water. were prepared by an innovative method involving hydrothermal synthesis at 150 °C using a mechanochemically synthesized zeolitic imidazolate framework (ZIF-8) titanium tetraisopropoxide as dioxide (TiO2) precursor. Three composite with different mass frac...

The rational design and facile construction of hybrid metal–organic framework (MOF) with hierarchical nanostructures can motivate novel multifunctional platforms to attain desirable performance. In this work, a new series MOF-on-MOF heterostructures, including ZIF-8/Zinc(II)-hexamethylenetetramine (ZIF-8/Zn-HMT) ZIF-8 + ZIF-67/Zn-HMT-X (ZIF/Zn-HMT-X), be conveniently synthesized by heteroepitax...

The effect of the mechanical deformation of metal-organic frameworks on guest diffusion was investigated by employing molecular dynamics simulations. Two basic deformation modes, uniaxial tensile and shear deformation, were considered. The computed shear modulus of the zeolitic imidazolate framework-8 (ZIF-8) model system was much lower than the Young's modulus, which is in agreement with the e...
