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 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 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 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 کاملPreparation, Characterization, and Application of Nanospherical α-Fe2O3 Supported on Silica for Photocatalytic Degradation of Methylene Blue
In the research, spherical α-Fe2O3 NanoParticles (NPs) were synthesized through Forced Hydrolysis and Reflux Condensation (FHRC) process and were supported on the surface of silica sand by Solid-State Dispersion (SSD) method. Characterization of silica and α-Fe2O3/SiO2 catalyst was done using Fourier-Transform InfraRed (FT-IR) spectrosc...
