May 11, 2023 · For this purpose, we target the ultramicroporous ZIF-62, a zeolitic imidazolate framework (ZIF) that has been used to produce MOF glass, to prepare a type of glass foam.

Mar 9, 2018 · We report the discovery of a new series of tetrahedral glass systems, zeolitic imidazolate framework–62 (ZIF-62) [Zn (Im 2−x bIm x)], which have ultrahigh GFA, superior to any other known glass formers.

Here, a mixed linker MOF ZIF-62 of the zeolitic imidazolate framework (ZIF) subfamily for TENG is reported. The structural and morphological analysis confirms the successful formation of ZIF-62. The Kelvin probe force microscopy (KPFM) and surface potential measurement reveal the positive potential on ZIF-62.

Jun 13, 2024 · Here, we present optical-quality glasses derived from the zeolitic imidazole framework ZIF-62 in the form of cm-scale objects. These allow for in-depth studies of optical transparency and...

Feb 2, 2024 · Herein, it is established that atomic layer deposition (ALD) of zinc oxide lends excellent control over the thickness and localization of resultant polycrystalline and glass zeolitic imidazole framework-62 (ZIF-62) thin-films within tubular α-alumina supports.

Dec 5, 2022 · Low-crystallinity ZIF-62 was synthesized by liquid-assisted mechanochemical method. The synthesized ZIF-62-L has reduced particle size and abundant open metal sites. The synthesized ZIF-62-L has improved CH 4 /N 2 selectivity of 7.3–8.4. Membrane with CH 4 permeance of 2726.6 GPU and CH 4 /N 2 selectivity of 3.96 was obtained.

Jan 19, 2025 · In-situ heating ZIF-62 glass can alleviate interfacial defects with membrane. High-loaded melting ZIF-62 glass membrane exhibits fast H 2 transport. The membrane has H 2 /CO 2 selectivity 23 and H 2 /CH 4 selectivity 57.

May 9, 2023 · This work first introduces a novel method to fabricate a bimetallic MOF glass, through melt-quenching of the cobalt-based zeolitic imidazolate framework (ZIF) [ZIF-62(Co)] with an adsorbed ferric coordination complex.

Mar 19, 2021 · Here, we have evaluated the adsorption properties of a nanoporous mixed-linker ZIF-62 using a combination of gas adsorption measurements, grand canonical Monte Carlo simulations, and synchrotron X-ray powder diffraction under operando conditions.

Feb 10, 2025 · The porous structure of glass ZIF-62 can be modified by changing the metal nodes (e.g., Co, Zn), hence affecting gas affinity and separation performance. The mixed-metal node glass ZIF-62 exhibits improved CO 2 /CH 4 selectivity, making it appropriate for natural gas purification and carbon capture applications.
