Low-coverage adsorption properties of the metal-organic framework amino-MIL-53 (Al) were determined using the pulse chromatographic technique. By using n-alkanes, iso-alkanes, 1-alkenes, cyclohexane and benzene as probe molecules, the nature of the adsorptive interactions in amino-MIL-53 (Al) was studied. Henry adsorption constants and adsorption enthalpies of iso-alkanes are significantly lowe...
To guarantee the security of new energy vehicles (NEV), which include storage devices such as batteries, a quartz crystal microbalance (QCM) sensor was designed to detect online HF gas produced from leakage electrolyte in power system. Based on chemical properties gas, an amino-functionalized metal–organic framework NH2-MIL-101 (Cr) synthesized sensing material QCM transducer for NEV safeguard....
Understanding the adsorption of water in metal−organic frameworks (MOF), and particularly in soft porous crystals, is a crucial prerequisite before considering MOFs for industrial applications. We report here a joint experimental and theoretical study on the behavior of a gallium-based breathing MOF, Ga-MIL-53, upon water adsorption. By looking at the energetics and thermodynamics of Ga-MIL-53,...
The synthesis on the gram scale and characterization of a series of flexible functionalized iron terephthalate MIL-53(Fe) type solids are reported. Chemical groups of various polarities, hydrophilicities, and acidities (-Cl, -Br, -CF(3), -CH(3), -NH(2), -OH, -CO(2)H) were introduced through the aromatic linker, to systematically modify the pore surface. X-ray powder diffraction (XRPD), molecula...
BACKGROUND Metal organic frameworks (MOFs) have attracted more attention in the last decade because of a suitable pore size, large surface area, and high pore volume. Developing biocompatible MOFs such as the MIL family as a drug delivery system is possible. PURPOSE Flurbiprofen (FBP), a nonsteroidal anti-inflammatory agent, is practically insoluble in aqueous solution, and, therefore, needs ...
Postsynthetic modification can be used to introduce sulfonamide functionalities into MOF frameworks. Using sulfonyl chlorides as reactive intermediates, Cr-MIL-SO3H and CAU-1-NH2 have been further modified to give hitherto unknown functionalized MOFs in which a sulfonamide group is bound to the framework either by its N or its S atom.
MIL-53(Fe) was synthesized using a “modulator approach” that utilizes acetic acid (HAc) as an additive to control the size and morphology of resulting crystals. We demonstrate after activation under vaccum at 100 °C, functions well for H2S selective oxidation. The introduction in presence benzene-1,4-dicarboxylic (H2BDC) would result series nanocrystals (denoted MIL-53(Fe)-xH, x stands volume a...
The adsorption mechanisms of three nonsteroidal anti-inflammatory drugs (NSAIDs), ibuprofen (IBP), ketoprofen (KET), and naproxen (NPX), applied onto a pristine 1D flexible framework MIL-53(Al) were compared with those adsorbed on MIL-53(Al)/alginate (AM) polyvinylidene fluoride/MIL-53(Al) (PM) composite beads through investigation single-solute batch fixed-bed systems. exhibited outstanding ca...
