Direct Solar Power‐Driven Durable Ammonia Electrosynthesis From Nitrate Under Fluctuating Voltage Conditions

Angewandte Chemie, EarlyView.
Isolated Sn sites on Cu(111) induce a highly asymmetric charge distribution, which promotes water dissociation, accelerates key intermediate hydrogenation, and suppresses competing hydrogen evolution. As a result, SnCu111 delivers NH3 Faradaic efficiencies above 90% over an 800 mV potential window and enables stable direct solar power‐driven NH3 ...

Electronegativity‐Guided Site Differentiation in High‐Entropy Alloy for pH‐Universal Hydrogen Evolution Reactions

Angewandte Chemie, EarlyView.
Electronegativity‐guided site differentiation is realized in a CoNiCuMoW high‐entropy alloy, where Co/Ni sites optimize hydrogen binding strength, Mo/W sites promote water dissociation, and Cu‐associated sites contribute to balanced hydrogen adsorption.

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

Proton‐Switching Regulates Interfacial Iodine Chemistry for Long‐Life Zinc–Iodine Batteries

Angewandte Chemie, EarlyView.
A proton‐switchable imine‐linked framework is developed to dynamically regulate interfacial iodine chemistry in aqueous Zn–I2 batteries, where reversible protonation/deprotonation switches the host affinity between iodide and polyiodide species. This state‐dependent regulation suppresses shuttle‐induced side reactions while preserving fast iodine redox

Defect‐Rich CoNi Prussian Blue Analogues Enable Highly Selective Electrochemical Hydrogen Peroxide Production

Angewandte Chemie, EarlyView.
Introducing [Co(CN)6]3− defects into CoNi Prussian Blue analogues exposes square‐planar Ni–N4 active sites, leading to remarkable H2O2 selectivity during the electrochemical oxygen reduction reaction in alkaline media. ABSTRACT Decentralized electrosynthesis of hydrogen peroxide (H2O2) via the two‐electron oxygen reduction reaction (2e− ORR) offers a ...
