The large-pore iron(III) carboxylate MIL-100(Fe) with a zeotype architecture has been isolated under hydrothermal conditions, its structure solved from synchrotron X-ray powder diffraction data, while Friedel–Crafts benzylation catalytic tests indicate high activity and selectivity for MIL-100(Fe).
The coordinatively unsaturated sites in MIL-101, Cr3(F,OH)(H2O)2O[(O2C)-C6H4-(CO2)]3⋅n H2O (n≈25), having zeotypic giant pores can be selectively functionalized a way differing from that of mesoporous silica. Metal–organic frameworks, grafted with ethylenediamine or diethylenetriamine on the CrIII exhibit remarkably high activities Knoevenagel condensation relative to mesophase.

Mesoporous MOFs MIL-100 and MIL-101 adsorb huge amounts of CO2 CH4. Characterization was performed using both manometry gravimetry in different laboratories for isotherms coupled with microcalorimetry FTIR to specify the gas—solid interactions. In particular, uptake carbon dioxide has been shown occur a record capacity 40 mmol g−1 or 390 cm3STP cm−3 at 5 MPa 303 K.
Recent ideas concerning site-selective functionalization of chromium terephtha-late MIL-101 are discussed, focusing on the utilization unsaturated Cr(III) sites (see image). advances in synthesis, selective surface functionalization, outstanding sorption properties, encapsulation nanoobjects, and catalytic applications also discussed.
Large hydrogen-storage capacity at liquid-nitrogen temperature is exhibited by the metal–organic framework MIL-101. In zeotype architecture of this porous solid (see picture) each intersection cages occupied a supertetrahedron formed trimers chromium octahedra assembled with benzene-1,4-dicarboxylate ligands.

Abstract Hemicellulose, the second, most common polysaccharide in nature constitutes approximately 20—35% of lignocellulosic biomass. Effective utilization biomass, hitherto underutilized, is gaining tremendous importance for production energy, fuels, and chemicals. Amongst vast array chemicals derived from lignocellulosics, furfural key chemical that finds wide applications oil refining, plastics, pharmaceutical agrochemical industries. There no synthetic route furfural. A few conventional...

The catalytic transfer hydrogenation (CTH) reaction is considered as a potential route for upgrading bio-based carbonyls to their corresponding alcohols. Herein, series of Zr-based metal−organic frameworks (Zr-MOFs) containing various types metal node ligand coordinations were synthesized and tested CTH furfural (FUR) furfuryl alcohol (FOL). It was found that coordination plays more important role than porosity in Zr-MOFs. MOF-808 (synthesized using scaled-up approach achieve higher batch...
Abstract The synthesis of the commercially available aluminum fumarate sample A520 has been optimized and its structure analyzed through a combination powder diffraction, solid‐state NMR spectroscopy, molecular simulation, IR thermal analysis. is an analogue MIL‐53(Al)‐BDC solid, but with more rigid behavior. differences between commercial samples in terms defects have investigated by situ spectroscopy correlated to their catalytic activity for ethanol dehydration.
A series of zirconium-based MOFs with different ligand functionalities and porosities were applied for catalytic transfer hydrogenation ethyl levulinate to form γ-valerolactone, using isopropanol as a hydrogen donor.
Nanoporosity, good thermal stability, antiferromagnetic ordering, and hydrogenation with basic catalytic character are four important properties of the large-pore (24MR), zeolitic nickel(II) phosphate, VSB-5 (Ni20 [(OH)12 (H2 O)6 ][(HPO4 )8 (PO4 )4 ]⋅12 H2 O), which has been prepared under alkaline hydrothermal conditions. The structure is depicted: NiO6 octahedra: green; PO4 tetrahedra: red.

The uptake and adsorption enthalpy of carbon dioxide at 0.2 bar have been studied in three different topical porous MOF samples, HKUST-1, UiO-66(Zr), MIL-100(Fe), after having pre-equilibrated under relative humidities (3, 10, 20, 40%) water vapor. If the case microporous UiO-66, CO(2) remained similar whatever humidity, correlations were difficult for HKUST-1 due to its instability toward In a remarkable 5-fold increase was observed with increasing RH, up 105 mg g(-1) 40% parallel large...
Copper/silica nanocomposite catalysts prove efficient for the direct hydrocyclization of biomass-derived levulinic acid to cyclic 2-methyltetrahydrofuran in vapor phase, at moderate hydrogen pressures.
