ZIF-8 and ZIF-67 containing various percentages of copper were successfully synthesized through a green in-situ thermal (IST) approach based on 2-methylimidazole (2-MIM) as the organic linker. The IST method has several advantages over previously reported studies, including solvent additive-free reaction conditions, mild temperature, single-step procedure, no activation requirements, use smalle...
−Metal organic frameworks (MOFs) are porous crystalline materials of one-, two-, or three-dimensional networks constructed from metal ions/clusters and multidentate organic linkers via coordination bonding, which are emerging as an important group of materials for energy storage, CO2 adsorption, alkane/alkene separation, and catalysis. To introduce newcomers in chemical engineering discipline t...
The comprehensive elastic properties of Zeolitic Imidazolate Frameworks (ZIF-1 to ZIF-4) have been computed using density functional theory (DFT). We employed the periodic CRYSTAL14 code to calculate the single-crystal elastic coefficients (Cij) at the B3LYP level of theory. While the chemical compositions of ZIFs-1 to -4 are the same, each structure features a distinct network topology, crysta...
Author(s): Dames, C; Urban, JJ; Kang, H | Abstract: Sugar alcohols (SAs) have attractive characteristics as phase-change materials, but their relatively high melting temperature limits application in the real world. Nanoconfinement can be a useful parameter to reduce pragmatic ranges. Using molecular dynamics simulations, we investigate phases and behaviors of encapsulated SA ZIF-8 ZIF-11, whic...
Zeolitic imidazolate frameworks (ZIFs) 7 and 9 are excellent candidates for CO2 adsorption and storage. Here, high-pressure X-ray diffraction is used to further understand their potential in realistic industrial applications. ZIF-7 and ZIF-9 are shown be able to withstand high hydrostatic pressures whilst retaining their porosity and structural integrity through a new ferroelastic phase transit...
Metal–organic frameworks (MOFs) are heralded as potential nanoplatforms for biomedical applications. Zeolitic imidazolate framework-8 (ZIF-8), one of the most well known MOFs, has been widely applied a drug delivery carrier cancer therapy. However, application ZIF-8 nanoparticles therapeutic agent hindered by challenge how to control release behaviour anti-cancer zinc ions cells. In this paper,...
Zeolitic imidazolate frameworks (ZIFs), a subclass of metal–organic (MOFs), have been widely investigated as additive in mixed matrix membranes (MMMs), but systematic studies to identify critical intrinsic ZIF-type parameters that determine the MMM performance are lacking. Therefore, three isoreticular gmelinite (GME) ZIFs, i.e., ZIF-68, 69 and 78 distinct by their partial different linkers, we...
ZIF-8 Modified Nanofiber Composite Window Screen for Efficient Indoor PM2.5 and Formaldehyde Removal
Because people spend a lot of time indoors every day, the presence particulate matter with diameter less than 2.5 µm (PM2.5) and volatile organic molecular substances in indoor air adversely affect public health. These toxic compounds can be removed from using high-efficiency air-filter materials adsorption capacity. Metal-organic frameworks (MOFs) are among most suitable for purification as th...
Composite sorbent materials (IL@MOF) with a metal-organic framework (MOF) ZIF-8 and [B(CN)4]?-based ionic liquids (ILs) were produced for the first time. Characterization results indicate successful IL impregnation conservation of crystalline structure morphology. The data collected from nitrogen (N2) physisorption at 77 K suggest that these IL@ZIF-8 are nonporous as their textural properties, ...
