In the FTIR spectrum of ZIF-7, the two intense absorption bands at 1460 and 736 cm − 1 are attributed to the stretching vibrational modes of the C--C and C-H bond of the benzene ring present...

2022年1月15日 · In this study, we report the synthesis of a novel γ-Fe 2 O 3 /ZIF-7 composite with a huge specific surface area using a simple precipitation route without surface premodification or stabilization. The resultant composite is evaluated for the selective removal of crude oil and other organic solvents from water.

2020年11月29日 · We report here fast (15 min) microwave-assisted solvothermal synthesis of zeolitic imidazolate framework material (ZIF-7). We have optimized solvent composition to achieve high porosity and hydrogen capacity and narrow particle size distribution.

2023年10月26日 · In this study, a novel graphene oxide/zeolitic imidazolate framework-7 (abbreviated as GO@ZIF-7) nanocomposite has been synthesized and utilized for the adsorptive removal of lead from aqueous solutions for the first time, to the best of our knowledge.

Solvent mixture controlled rapid room temperature syntheses for facile access to uniform zeolitic-imidazolate framework nanocrystals (ZIF-7, ZIF-65-Zn and ZIF-71) are reported. ZIF thin...

2019年12月1日 · Zeolitic imidazolate framework ZIF-7 (Zn (bim) 2) is a prototypical one among different ZIFs, and it is formed by connecting Zn actions with benzimidazole (bim) anions. Single crystal X-Ray diffraction studies shows it has a sodalite (SOD) topology with a …

2022年5月1日 · We report the chemical stability of ZIF-7 under pressure using Raman spectroscopy. Our results show a reversible pressure response of ZIF-7 in non-penetrating media up to 8 GPa. Increasing pressures above 12 GPa leads to an irreversible ring-opening polymerization to a disordered phase.

2020年2月5日 · In order to reduce the fire risk of rigid polyurethane foams (RPUF), three kinds of zeolitic imidazolate frameworks (ZIFs) were prepared. The results of Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM and X-ray diffraction (XRD) showed that ZIFs were successfully prepared.

ZIF-7 and ZIF-11 were successfully synthesized and characterized with SEM, FTIR, XRD and water contact angels, exhibiting unique and excellent stability, spatial structure and chemical composition, promising for environmental PAHs efficient enrichment through hydrophobic, π–π and π-complexation interactions.
