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...

We performed ab initio calculations of the elastic constants of five flexible metal-organic frameworks (MOFs): MIL-53(Al), MIL-53(Ga), MIL-47, and the square and lozenge structures of DMOF-1. Tensorial analysis of the elastic constants reveals a highly anisotropic elastic behavior, some deformation directions exhibiting very low Young's modulus and shear modulus. This anisotropy can reach a 400...

1. Introduction The presence of organic part in the new class of hybrid solids imparts an important chemical versatility to these materials compared to "classical" solids. The architecture of Metal Organic Frameworks (MOF) may lead to open structures with 1D (chains), 2D (layers) or 3D dimensionality developing very large surface areas (above 1000 m 2 /g) [1]. Some MOFs possess a structural ori...

The metal-organic framework, MIL-53, can have a structural transition from an open-pored to a closed-pored structure by adsorbing different guest molecules. The aid of guest molecules is believed to be necessary to initiate this "breathing" effect. Using both neutron powder diffraction and inelastic neutron scattering techniques, we find that MIL-53 exhibits a reversible structural transition b...

Organic semiconductors are promising materials for the photocatalytic treatment of pollutants and organic synthesis. Herein, MIL-53(Fe)@perylene diimide (PDI) heterojunctions were constructed by ultrasonic assembly using PDI as co-catalyst, supramolecular material was uniformly distributed on surfaces MIL-53(Fe). The most effective M53@PDI-20 achieved 72.7% photodegradation rhodamine B (10 mg/L...

asymmetrically mixed matrix matrimid-mil-53 membranes with silicone cover layer were fabricated. for better understanding of membrane fabrication process, three main parameters of fabrication, matrimid concentration, silicone concentration and weight percentage of metal organic framework (mil-53) particles, were optimized by an experimental design method. cross-section sem images were used to s...
