In contrast to catalytically active metal single atoms deposited on oxide nanoparticles, the crystalline nature of metal-organic frameworks (MOFs) allows for a thorough characterization reaction mechanisms. Using defect-free HKUST-1 MOF thin films, we demonstrate that Cu
A novel catalytic asymmetric dienylation of para-quinone methides with allenoates has been developed. Under mild conditions catalyzed by (R)-SITCP, various dienylated bisarylmethides were obtained in moderate to good yields (up 82% yield) and excellent enantioselectivities (90–98% ees). The efficacy robustness demonstrated 27 examples chiral products. plausible mechanism, which involved 1,2 H-shift umpolung allenoates, was proposed based on deuterium labeling experiments previous reports.
Adding hydrophilic ligands into aqueous solutions for the selective binding of actinides(III) is acknowledged as an advanced strategy in Ln(III)/An(III) separation. In view recycling and radioactive waste disposal minor actinide, there remains urgent need to design develop appropriate ligand separation An(III) from Ln(III). Herein, four novel with hard–soft hybrid donors, derived pyridine phenanthroline skeletons, were designed synthesized masking agents complexation phase. The known...
Catalytic studies traditionally rely on steady-state conditions resulting in time-averaged datasets that do not differentiate between active and spectator species. This limitation can cause misinterpretations of catalytic function, as the signal short-lived intermediates responsible for producing desired reaction products is often masked by more intense Time-resolved ambient pressure X-ray photoelectron spectroscopy (tr-APXPS) mitigates this issue combining microsecond time resolution under...
A series of new defect-engineered metal–organic frameworks (DEMOFs) were synthesized by framework doping with truncated linkers employing the mixed-linker approach. Two tritopic defective (truncated) linkers, biphenyl-3,3′,5-tricarboxylates (LH) lacking a ligating group and 5-(5-carboxypyridin-3-yl)isophthalates (LPy) bearing weaker interacting ligator site, integrated into Cu2(BPTC) (NOTT-100, BPTC = biphenyl-3,3′,5,5′-tetracarboxylates). Incorporating LH mainly generates missing metal node...
Reaction products in heterogeneous catalysis can be detected either on the catalyst surface or gas phase after desorption. However, if atoms are dissolved bulk, then reaction channels become hidden. This is case dissolution rate of deposits faster than their formation rate. might lead to underestimation even overlooking such as, e.g., carbon deposition during hydrocarbon oxidation reactions, which problematic as have a significant influence catalytic activity. Here, we demonstrate how hidden...
The embedding of metal nanoparticles in MOFs is highly relevant catalysis research. MOF matrix prevents the NMP agglomeration. Furthermore, can easily be functionalized to design an optimal chemical environment for benefit a catalytic reaction. We report on series [email protected] materials, namely and protected]nip, consisting structural prototype CuBTC (= [Cu3BTC2]; BTC = benzene-1,3,5-tricarboxylate). Pd NPs were incorporated by rapid “bottle-around-the-ship” encapsulation. Regulation...
Defect engineering (DE) has been recognized as a powerful approach to tune the structural, optical, and chemical properties of metal–organic framework (MOF) materials. Here, detailed characterization using ultrahigh-vacuum Fourier-transform infrared spectroscopy X-ray photoelectron was performed for defect-engineered NOTT-100 (Cu2(BPTC), BPTC = biphenyl-3,3′,5,5′-tetracarboxylates). Defects were introduced either via thermal defect (TDE) or defective linker (synthetic engineering, SDE). A...
Information on structural, chemical and physical properties of natural cleaved (10.4) calcite surfaces was obtained by a combined atomic force microscopy infrared study using CO as probe molecule under ultrahigh vacuum conditions.
Nanoporous gold (NPG) is a versatile, nanoporous bulk material with applications in catalysis, sensors, energy materials, and actuation. NPG obtained from dealloying Ag-rich Au–Ag alloys has interesting electrocatalysis, for which methanol oxidation an test case. Such materials always contain content of residual silver may play role activating binding reaction intermediates. The Ag that contained due to the Ag–Au alloy was recently found be present silver-rich islands, contrast being...
Ambient pressure x-ray photoelectron spectroscopy (APXPS) can provide a compelling platform for studying an analyte's oxidation and reduction reactions in solutions. This paper presents proof-of-principle operando measurements of model organometallic complex, iron hexacyanide, aqueous solution using the dip-and-pull technique. The data demonstrates that electrochemically active liquid meniscuses on working electrodes undergo controlled redox which were observed APXPS. A detailed discussion...
An interesting remote δ-C 1,6-addition and an isomerization cascade reaction for phosphine-catalyzed activated alkynes have been disclosed. The products featuring a functional diene 1,1-diaryl methyl motif obtained in moderate to good yields (30–86%) by applying para-quinone methides (p-QMs) δ-substituted alkynoate with tributylphosphine (PnBu3) catalysis, along high regioselectivity stereoselectivity (dr > 20:1). wide scope of compatible substrates (35 examples), such as indolyl, oxindolyl,...
Abstract Im Gegensatz zu einzelnen, auf Oxid‐Nanopartikeln deponierten katalytisch aktiven Metalllatomen erlaubt die kristalline Beschaffenheit metallorganischer Gerüstverbindungen (MOFs) eine genaue Charakterisierung der Reaktionsmechanismen. Ausgehend von zunächst defektfreien HKUST‐1‐MOF‐Dünnschichten zeigen wir, dass Cu + /Cu 2+ ‐Dimerdefekte, kontrolliert durch Reduktion reinen ‐Paare des intakten Gerüsts erzeugt wurden, hohe katalytische Aktivität für Tieftemperatur‐CO‐Oxidation...
