Zeolitic imidazolate framework-8 (ZIF-8) is synthesized quickly at room temperature in methanol with the support of ultrasound. Porous ZnO also prepared via thermal treatment ZIF-8. The photocatalytic activities obtained materials are demonstrated methylene blue (MB) decomposition under UV radiation. characterized by means X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR)...

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...

−Metal organic frameworks (MOFs) are porous crystalline materials of one-, two-, or three-dimensional networks constructed from metal ions/clusters and multidentate organic linkers via coordination bonding, which are emerging as an important group of materials for energy storage, CO2 adsorption, alkane/alkene separation, and catalysis. To introduce newcomers in chemical engineering discipline t...

This work presents for the first time a zeolitic imidazolate framework (ZIF)-coupled resonant gas sensor whose sensitivity shows an improvement up to 78 times over bare silicon resonant sensors with identical dimensions. ZIFs are among the highest surface area material used for resonant-based sensing. We utilize high surface area-to-volume ratios of ZIFs to demonstrate how a microresonator coup...

Water is life, and clean-water demand increasing daily as a result of rapid population growth industrial evolution. Nevertheless, due to the inadequate supply availability new water sources, there need for effective, sustainable removal contaminants wastewater reuse. Several treatment approaches that include chemical, physical, biological methods have been thoroughly tested, with being regarded...

We study the adsorption equilibrium isotherms and differential heats of adsorption of hexane isomers on the zeolitic imidazolate framework ZIF-8. The studies are carried out at 373 K using a manometric set-up combined with a micro-calorimeter. We see that the Langmuir model describes well the isotherms for all four isomers (n-hexane, 2-methylpentane, 2,2-dimethylbutane and 2,3-dimethylbutane). ...

Membrane technology for water treatment is growing due to the increased demand clean and stringent standard quality. Nanofiltration (NF) widely used in membranes lower energy consumption higher flux rates. The application was not limited only treatment, yet NF showed excellent potential solvent nanofiltration application. utilization of MOF materials preparation produce composite has attracted ...

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...

Humidity effects on resistive gas sensors operating at room temperature remain a serious bottleneck. In this work, we introduce sensor based zeolitic imidazolate framework-8/carbon nanotube (ZIF-8/CNT) composite for the detection of ammonia temperature. The was prepared using facile solution method. sensor, basic mechanism charge transfer between molecules and CNTs; meanwhile, ZIF-8 facilitated...
