The effect of typical membrane processing conditions on the structure, interfacial morphology, and gas separation performance of MOF/polymer nanocomposite membranes is investigated. In particular, the ZIF...

Polymer supported ZIF-8 membranes prepared via an interfacial synthesis method.

Porous polymer supported continuous ZIF-8 membranes were prepared via an interfacial synthesis method. Membranes with only one synthesis cycle showed excellent performance in the nanofiltration range.

Improving Sensitivity of a Chemoresistive Hydrogen Sensor by Combining ZIF-8 and ZIF-67 Nanocrystals

In the present work, nanostructures of zeolitic imidazolate frameworks (ZIF-8 and ZIF-67) were combined to obtain a novel chemoresistive sensor, improving the sensitivity of ZIF-67 and facilitating measurement of ZIF-8 by decreasing the resistivity. The sensor detected concentrations as low as 10 ppm of hydrogen increasing its resistivity about 4.5 times. The response of the sensor was compared...

Porous Proton Exchange Membrane Based Zeolitic Imidazolate Framework-8 (ZIF-8)

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 ...
