چکیده
Excess adsorption of CO2, CH4, N2, and H2 on ZIF-8 was measured gravimetrically in the pressure range ranging from vacuum to 30 MPa at 298.15, 313.15, 333.15, 353.15, 394.15 K using a magnetic suspension balance. The textural properties adsorbent material?i.e., skeletal density, surface area, pore volume, pore-size distribution?were estimated by helium gravimetry N2 (77 K) physisorption. isotherms were fitted with Sips isotherm model virial equation, values isosteric heat Henry constants for gases determined latter.

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 کاملRapid synthesis of zeolitic imidazolate framework-8 (ZIF-8) nanocrystals in an aqueous system.
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.
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...
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 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...
