Mixed matrix membranes (MMMs) composed of metal organic framework (MOF) fillers embedded in a polymeric represent promising alternative for CO 2 removal from natural gas and biogas. Here, MMMs based on NH ‐MIL‐53(Al) MOF polyimide are successfully synthesized with loadings up to 25 wt% different thicknesses. At 308 K ΔP = 3 bar, the incorporation filler enhances permeability respect neat polymer, while preserving relatively high separation factor. The rate solvent evaporation after membrane...
Mixed‐matrix membranes comprising NH 2 ‐MIL‐53(Al) and Matrimid or 6FDA‐DAM have been investigated. The metal organic framework (MOF) loading has varied between 5 20 wt%, while with three different morphologies, nanoparticles, nanorods, microneedles dispersed in Matrimid. synthesized tested the separation of CO from CH 4 an equimolar mixture. At 3 bar 298 K for 8 wt% MOF loading, incorporation nanoparticles leads to largest improvement compared nanorods microneedles. best performing filler,...
It has been found that a bifunctional metal Pd/base (MgO) catalyst performs the selective monoalkylation of amines with alcohols. The reaction goes through series consecutive steps in cascade mode involves: 1) abstraction hydrogen from alcohol produces hydride and carbonyl compound; 2) condensation amine to give an imine, 3) hydrogenation imine surface atoms hydride. Based on isotopic spectroscopic studies rate each elementary step, global mechanism proposed. controlling step process is...
Abstract During the last decade, synthesis and application of metal–organic framework (MOF) nanosheets has received growing interest, showing unique performances for different technological applications. Despite potential this type nanolamellar materials, synthetic routes developed so far are restricted to MOFs possessing layered structures, limiting further development in field. Here, a bottom‐up surfactant‐assisted approach is presented fabrication various nonlayered MOFs, broadening scope...
Thiols are smoothly and efficiently oxidized to disulfides (RSSR) with air in the presence of gold nanoparticles supported on CeO2 absence solvent, as well aqueous solutions neutral pH. It is shown that reaction can occur through coupling two sulphur radicals metal surface. The formed from thiols by one-electron oxidation metal. This mechanism strongly resembles found for sulfhydryl oxidases, a class enzymes which involved oxidative protein folding de novo formation thiols.
By taking inspiration from the catalytic properties of single-site catalysts and enhancement performance through ionic liquids on metal catalysts, we exploited a scalable way to place single cobalt ions carbon-nanotube surface bridged by polymerized liquid. Single dispersed coordinated liquid are used as heterogeneous for oxygen evolution reaction (OER). Performance data reveals high activity stable operation without chemical instability.
The selective conversion of syngas to higher alcohols is an attractive albeit elusive route in the quest for effective production chemicals from alternative carbon resources. We report tandem integration solid cobalt Fischer-Tropsch and molecular hydroformylation catalysts a one-pot slurry-phase process. Unprecedented selectivities (>50 wt %) C2+ are achieved at CO levels >70 %, alongside negligible CO2 side-production. efficient overall transformation enabled by catalyst engineering,...
Abstract The development of effective and precious‐metal‐free electrocatalysts for the oxygen evolution reaction (OER) represents a major bottleneck to unlock renewable energy scenario based on water splitting technologies. Materials uniting electrical conductivity conjugated graphitic nanomaterials with chemical regularity metal‐organic‐framework (MOF) crystals are promising precursors such electrocatalysts. Nanoscale integration these two materials is challenging. A new synthesis route...
Abstract Palladium on magnesium oxide is able to allow a one‐pot reaction synthesize thioethers from thiols and aldehydes formed in situ the respective alcohol by means of borrowing hydrogen method. The initiated dehydrogenation give palladium hydride intermediate an aldehyde. latter reacts with thiol involving most probably intermediacy thionium ion RCHS + R, which can be reduced metal afford thioethers.

Tandem catalysis stands out as a major instrument towards the intensification of existing and future chemical processes. Initially formulated in field homogeneous catalysis, concept relies on single-pot integration two (or more) catalysts showing high specificity for mechanistically decoupled reactions, while being operational compatible under single set operation conditions. Isolated metal atoms stabilized solid carriers single-atom (SACs) hold potential to reconcile reaction specificities...
Focused ion beam-scanning electron microscopy (FIB-SEM) sheds light on the performance of MOFbased mixed matrix membranes. On page 249, 3D tomography is presented by T. Rodenas, J.
