Vacuum‐Induced Surface Reconstruction of Mn–Ce Oxides for Low‐Temperature Coupled Redox Catalysis

Angewandte Chemie, EarlyView.
Near‐surface reconstruction enhances low‐temperature redox catalysis in Mn–Ce mixed oxides. Sequential vacuum annealing and reduced‐pressure O2 treatment enrich Mn near the surface while preserving the CeO2 fluorite framework, promoting interfacial electron redistribution, oxygen activation, and redox cycling.

Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

Angewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

Controlled Hydrogen Delivery by Single‐Atom Ru Accelerates Electrocatalytic Ammonia Synthesis

Angewandte Chemie, EarlyView.
Single Ru atoms anchored on Co3O4 guide reactants along a hydrogen‐rich surface pathway, enabling efficient and selective conversion of NO to NH3. By linking atomic design to catalytic performance, this strategy clarifies the reaction mechanism and offers a versatile platform for engineering oxide catalysts for electrochemical ammonia synthesis ...

Gold Clusters With Open‐Shell Ligands: Superatom Mediated Magnetic Interaction

Angewandte Chemie, EarlyView.
Open‐shell verdazyl radicals were covalently integrated with atomically precise Ir‐doped Au12 (Ir@Au12) superatoms. The resulting radical–superatom hybrids exhibit photoinduced electron transfer, spin delocalization onto the metal‐cluster core, and weak ferromagnetic communication between radicals mediated by the superatomic electronic structure ...

Axially Chiral Nonalternant Polycyclic Aromatic Hydrocarbon With Consecutive Pentagons Exhibiting Large Spin‐Polarized Current

Angewandte Chemie, EarlyView.
Here we report two nonalternant polycyclic aromatic hydrocarbons (PAH) (1 and 2), which contain two and four consecutive pentagons, respectively. Under acidic conditions, 1 and 2 dimerize to afford the axially chiral dimers AC1 and AC2. The central azulene moiety in both 2 and AC2 shows an unusually short transannular bond of 1.366 Å.
