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 ...
متن کاملReversed Crystal Growth of RHO Zeolitic Imidazolate Framework (ZIF)
RHO zeolitic imidazolate framework (ZIF), Zn1.33 (O.OH)0.33 (nim)1.167 (pur), crystals with a rhombic dodecahedral morphology were synthesized by a solvothermal process. The growth of the crystals was studied over time using scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (PXRD) and Brunauer-Emmett-Teller (BET) analyses, and a reversed crysta...
متن کاملDielectrophoresis-assembled zeolitic imidazolate framework nanoparticle-coupled resonators for highly sensitive and selective gas detection.
This work reports on zeolitic imidazolate framework (ZIF)-coupled microscale resonators for highly sensitive and selective gas detection. The combination of microscale resonators and nanoscale materials simultaneously permits the benefit of larger capture area for adsorption from the resonator and enhanced surface adsorption capacity from the nanoscale ZIF structure. Dielectrophoresis (DEP) was...
متن کاملOpening ZIF-8: a catalytically active zeolitic imidazolate framework of sodalite topology with unsubstituted linkers.
A zeolitic imidazolate framework material of SOD topology possessing primarily unsubstituted imidazolate (im) linkers has been synthesized via solvent-assisted linker exchange (SALE) of ZIF-8. The structure of the new material, SALEM-2, has been confirmed through (1)H NMR and powder and single-crystal X-ray diffraction. SALEM-2 is the first example of a porous Zn(im)(2) ZIF possessing a truly z...
متن کاملImmobilization of lysozyme proteins on a hierarchical zeolitic imidazolate framework (ZIF-8).
A hierarchical zeolitic imidazolate framework-8 (micro/meso-ZIF-8) was fabricated by using cetyltrimethylammonium bromide as a structure-controlling agent and l-histidine as co-templates. Compared to the conventional microporous ZIF-8 (micro-ZIF-8), the hierarchical porous structure of micro/meso-ZIF-8 contains micropores and maximum mesopores of around 35.6 nm. The as-prepared hierarchical mic...
