Zeolitic imidazolate framework (ZIF-8) nanocrystals were uniformly grown on the surface of cellulose (CNCs) to give a hybrid material, [email protected] By varying stoichiometry components, it was possible control size ZIF-8 crystals CNC surface. Optimized ([email protected]) used as template synthesize microporous organic polymer (MOP), protected]@CNC. After etching with 6 M HCl solution, MOP ...

In this research, ZnO nanorods were utilized as gas sensor materials for detecting toluene vapour and hydrogen prior to following the use of Zeolitic imidazolate frameworks-8 (ZIF-8) filter. On porous Al2O3, ZIF-8 was deposited thickness 200 nm. Scanning electron microscope (SEM), XRD, sensing tests used examine material characteristics regarding ZnO. Thin films' sensitivity selectivity differe...

Zeolitic imidazolate framework-8 nanoparticles (ZIF-8 NPs) are typical metal–organic framework (MOF) materials and have been intensively studied for their potential application in drug delivery environmental remediation. However, knowledge of risks to health the environment is still limited. Therefore, this study exposed female male zebrafish ZIF-8 NPs (0, 9.0, 90 mg L−1) four days. Subsequentl...

Owing to their permanent porosity, diverse topology structures, and coordination factors combined with chemical tunability, the zeolitic imidazolate framework (ZIF) has shown great potential for effective separation of hydrocarbon mixtures. In this work, authors presented a simple microwave-assisted seeding strategy rapidly prepare seed layer synthesis high-quality ZIF-8 membranes propylene/pro...

The search for efficient water oxidation catalysts (WOCs) is of paramount importance in energy and environmental fields, but there exists no good non-noble catalyst that works under acidic and alkaline conditions. Intensive investigations have recently focused on cobalt based complex/solid catalysts. Here, we have introduced a new type of cobalt-based WOC made of metal-organic frameworks where ...

The peptide-based porous 3D framework, ZnCar, has been synthesized from Zn(2+) and the natural dipeptide carnosine (β-alanyl-L-histidine). Unlike previous extended peptide networks, the imidazole side chain of the histidine residue is deprotonated to afford Zn-imidazolate chains, with bonding similar to the zeolitic imidazolate framework (ZIF) family of porous materials. ZnCar exhibits permanen...

In recent years, the vapor deposition of zeolitic imidazolate framework-8 (ZIF-8) has gained high attraction due to its good scalability, conformality, and thickness control. The present study provides new fundamental insights regarding ZIF-8 from zinc oxide (ZnO). During synthesis, ZnO thin films with different percentages open porosity (14.5%–24%) were subjected a 2-methylimidazole for conver...

Herein, we present the first examples of solvent-assisted linker exchange (SALE) in zeolitic imidazolate frameworks (ZIFs). By exposing the ZIF CdIF-4 to excess solutions of 2-nitroimidazole and 2methylimidazole under solvothermal conditions, we were able to obtain a previously reported ZIF CdIF-9 in high yield, as well as synthesize a new ZIF, Solvent-Assisted Linker-Exchanged Material-1 (SALE...

Because people spend a lot of time indoors every day, the presence particulate matter with diameter less than 2.5 µm (PM2.5) and volatile organic molecular substances in indoor air adversely affect public health. These toxic compounds can be removed from using high-efficiency air-filter materials adsorption capacity. Metal-organic frameworks (MOFs) are among most suitable for purification as th...

Toluene was discovered as the structure template for the synthesis of large-cage RHO-type zeolitic imidazolate frameworks (ZIF-11 and ZIF-12) in an alcohol-based solution where benzimidazole-toluene interactions play a decisive structure-directing role; otherwise it leads to small-cage SOD-type ZIF-7 and ZIF-9 without toluene. The specific π-π interactions make toluene molecules adopt a specifi...
