Hydrogen storage in a prototypical zeolitic imidazolate framework-8.
Zeolitic imidazolate frameworks (ZIFs) are a new class of nanoporous compounds which consist of tetrahedral clusters of MN4 (M ) Co, Cu, Zn, etc.) linked by simple imidazolate ligands.1,2 As a subfamily of metal-organic frameworks (MOFs), ZIFs exhibit the tunable pore size and chemical functionality of classical MOFs. At the same time, they possess the exceptional chemical stability and rich st...
متن کاملQuasi-free methyl rotation in zeolitic imidazolate framework-8.
Using neutron inelastic scattering and diffraction, we have studied the quantum methyl rotation in zeolitic imidazolate framework-8 (ZIF-8: Zn(MeIM)(2), MeIM = 2-methylimidazolate). The rotational potential for the CH(3) groups in ZIF-8 is shown to be primarily 3-fold in character. The ground-state tunneling transitions at 1.4 K of 334 +/- 1 mueV for CH(3) groups in hydrogenated ZIF-8 (H-ZIF-8)...
متن کاملPorous 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 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...
