The Promise and Challenges of Ammonia Electrosynthesis From Dinitrogen and Water Using an Electrochemical Palladium Membrane

Angewandte Chemie, EarlyView.
Electrosynthesis of ammonia from nitrogen gas and water at ambient temperature is demonstrated using a device equipped with an electrochemical palladium membrane, which provides exclusive selectivity for the transfer of protons between the aqueous water oxidation and non‐aqueous nitrogen reduction compartments.

Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor

Angewandte Chemie, EarlyView.
A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...

Pt‐Mediated Co‐Adsorption of Hydroxyl and Nitrogen‐Heterocyclic Species Over Cu/CuO Heterostructure Enhances Coupled Azotriazole Electrosynthesis and Dual‐Electrode Hydrogen Production

Angewandte Chemie, EarlyView.
Pt@Cu/CuO heterostructures were designed for electrochemical N─N coupling of 3,5‐diamino‐1H‐1,2,4‐triazole. Mechanism investigation revealed that the Pt sites mediated co‐adsorption of substrates and hydroxyl on Cu/CuO sites. The elaborate Pt@Cu/CuO achieved an ultralow working potential of 0.832 VRHE with a high FE of 95%. A long‐term stability of 600

Defined Dinuclear Nickel Sites on Mesoporous Silica Translate Molecular Surface Mimics to Heterogeneous Catalysis

Angewandte Chemie, EarlyView.
The cooperative reactivity characteristic of molecular dinuclear nickel complexes is transferred to mesoporous silica through a systematic immobilization strategy. The resulting material preserves the key features of the bimetallic motif within a robust heterogeneous framework, demonstrating how molecular design principles can be translated into well ...

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.

Dual d–p hybridization in Ternary PtGaGe Enables Concurrent Activity and Stability Enhancement for Alkaline Oxygen Reduction

Angewandte Chemie, EarlyView.
A unique dual d–p orbital hybridization strategy was established in a ternary PtGaGe alloy catalyst to overcome the longstanding activity–stability trade‐off in oxygen reduction reaction (ORR). Synergistic hybridization between Ga/Ge p orbitals and Pt d orbitals modulates the Pt electronic structure, optimizes oxygen intermediates adsorption, and ...

Intramolecular Nickel‐Catalyzed Reductive Coupling: Enantioselective Synthesis of Tetrahydroisoquinolines and Related Heterocycles

Angewandte Chemie, EarlyView.
The successful extension of the nickel‐catalyzed asymmetric coupling of polarized 1,3‐dienes with aldehydes to an intramolecular setting opens an efficient new entry into hydroxylated N‐heterocyclic compounds, most notably valuable tetrahydroisoquinolines.
