The use of metal-organic frameworks (MOFs) in the polymerization field remains comparatively rare up to now, let alone studies on the fabrication of polymer microstructures through a MOFs-catalyzed assembly process. Zeolitic imidazolate framework-8 (ZIF-8), a well-known MOF for its chemical and thermal stabilities, was used to induce a polymerization reaction of saturated alkylsilanes for the f...
Tetraaminoporphyrin (TAPP) sensitized ZIF-8 was successfully prepared by one-pot method as an efficient visible light photocatalyst. The photocatalyst TAPP/ZIF-8 characterized XRD and SEM. combination of TAPP enhances the absorption light, effectively improves electron-hole separation, photocatalytic activity under light. In experiment, showed good performance for removal Rhodamine B (RhB) Ther...
A facile two-step strategy was developed to fabricate yellow fluorescent glutathione-Au nanoclusters/zeolitic imidazolate framework-8 nanoparticles (GSH-Au NCs/ZIF-8 NPs) and their derived Au/ZnO NPs, which exhibited visible light photocatalytic hydrogen evolution together with degradation of Rhodamine B (RhB).
ZIF-8 films were successfully prepared on a flexible nylon substrate with a contra-diffusion synthesis method, and gas permeation experiments indicated that the films were continuous and compact.
Abstract Membrane‐based separations offer energy‐efficient solutions for various applications, but commercial polymer membranes show limited performance and stability. Mixed‐matrix (MMMs), incorporating nanoporous inorganic materials in matrices, have been of great interest to circumvent these polymer‐specific issues. However, reaching the percolation threshold is crucial leverage high‐performi...
The elastic properties of a zeolitic metal-azolate framework, Zn(mtz)2 (MAF-7, mtz− = 3methyl-1,2,4-triazolate), have been examined from the view point of the first principles calculations and experiments. Our results demonstrate that the three independent elastic constants of MAF-7 are about 5.0–73.3% higher than those of ZIF-8, though they are isomorphic. The electron-donating effect of the n...
