We report here the first example of ZIF materials synthesized in aqueous solution. The synthesis was performed at room temperature and typically took several minutes compared to hours and days in non-aqueous conditions. The obtained product were ZIF-8 nanocrystals having size of ~85 nm and showed excellent thermal, hydrothermal and solvothermal stabilities.

This work presents a simple effective strategy to synthesize N-doped and shell-controlled carbon nanocages through package baking approach. A green approach core-shell ZIF-8@PTZ nanoparticles involves zinc contained ZIF-8 core wrapped by N-enriched polytriazine (PTZ). Synthesized are calcinated further sublime PTZ shell washed HCl, leaving porous structure. At the meantime, hollow cavities were...

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). ...

Lithium-selenium battery is nowadays a highly competing technology to the commercial Li-ion because it has high volumetric capacity of 3253 mAh cm-3 and gravimetric 675 g-1. However, practical application lithium-selenium (Li-Se) batteries impeded by shuttle effect soluble polyselenides during cycling process. Herein, we report in situ growth pyrolysis metal-organic framework zeolitic imidazola...

Metal-organic frameworks (MOFs) are emerging material class for the past few years due to its tailorability characteristics for various applications. However, the research and development (R&D) of MOFs is still scarce for fuel cell system. This may be due to the several difficulties faced in selecting a good MOFs-based electrolyte, which consequently affects both proton conduction and methanol ...

Because of the high separation performance and easy preparation, mixed-matrix membranes (MMMs) consisting of metal-organic frameworks have received much attention. In this article, we report a novel ZIF-300/PEBA MMM consisting of zeolite imidazolate framework (ZIF-300) crystals and polyether block amide (PEBA) matrix. The ZIF-300 crystal size was effectively reduced by optimizing the hydrotherm...

Zinc 2-methylimidazolate (Zn(Me-Im)2, ZIF-8) was synthesized through solvothermal method, and the Mn@ZIF-8 by loading Mn species onto prepared ZIF-8 impregnation. The effect of addition amount for activity in selective catalytic reduction NOx with NH3 (NH3-SCR), stability catalysts at ideal temperature conditions resistance to H2O SO2 were investigated. Moreover, characterizations including XRD...

Mixed matrix membranes (MMM) incorporating metal-organic framework (MOF) fillers have gained increasing attention in addressing environmental and sustainability challenges. Hierarchical materials combining pore sizes of different length scales are expected to facilitate molecular diffusion mass transfer for the optimization catalysis separation processes. Herein, a novel preparation method hier...
