Tailoring High‐Valent Iron‐Oxo Species Redox via Extended π‐Fe3d–O2p Orbital Overlapping Toward Chemical‐Efficient Water Purification

Angewandte Chemie, EarlyView.
We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...

Cycloazulenylen

Angewandte Chemie, EarlyView.
Ein ausschließlich aus Azulen‐Untereinheiten aufgebauter gespannter Makrocyclus mit der Bezeichnung [6]Cycloparaazulenylen ([6]CPA) wird vorgestellt. Der Makrocyclus weist für ein Azulensystem eine bemerkenswert kleine HOMO–LUMO‐Energielücke, eine durch die Ringspannung hervorgerufene bathochrome Verschiebung der Absorption sowie ein ungewöhnliches ...

Positive Electrochemical Potentials Induce Enhanced Chemoselectivity and Activity in the Thermocatalytic Hydrogenation of 3‐Nitrostyrene

Angewandte Chemie, EarlyView.
Induced by positive electrochemical potentials, thermocatalytic hydrogenation (TCH) of 3‐nitrostyrene with H2 delivers one single product with six‐fold enhanced yield. The enhanced selectivity and activity originate from changes in the adsorption geometry of 3‐nitrostyrene and in the surface concentration of 3‐nitrostyrene and hydrogen via a concurrent

Crosslinking of Linear Polyimines Into Aminal‐Linked Porous Organic Polymers for C2 Hydrocarbon/Methane Separation

Angewandte Chemie, EarlyView.
Crosslinking of linear polyimines with aromatic diamines via nucleophilic addition converts nonporous polyimine precursors into aminal‐linked porous networks, offering a new strategy for synthesizing porous organic polymers. The resulting materials exhibit high C2 hydrocarbon adsorption capacity, excellent selectivity over CH4, and durable cyclic ...

Eine kohlenstoffinduzierte Oberflächenrekonstruktion auf einem Fischer‐Tropsch‐Katalysator im Betrieb

Angewandte Chemie, EarlyView.
Nach einer weitverbreiteten Annahme erfährt der Cobalt‐basierte Fischer‐Tropsch‐Katalysator eine anfängliche Aufrauung, die zu einer Aktivitätssteigerung führt und vom hohen chemischen Potential des Kohlenstoffs getrieben wird. In der vorliegenden Operando‐STM‐ und DFT‐Untersuchung simulieren wir solche Bedingungen.

Acceptor‐Doped Cerium Oxides Enabling Metallic Nanocatalyst Exsolution for Hydrogen Production From Ammonia

Angewandte Chemie, EarlyView.
Outstanding catalytic results for NH3 decomposition for H2 production were obtained with metallic Ru, Rh, and RuRh nanoparticle‐exsolved CeO2‐based catalysts. Significant lower amounts of available superficial metallic fractions were needed in comparison to conventional Ru‐impregnated materials.
