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 ...

Red Light‐Gated Charge Transfer Enables Trace Oxygen Response in Dye‐Sensitized TiO2–Carbon Nanotube Hybrids

Angewandte Chemie, EarlyView.
Light activation allows spatiotemporal control over materials, yet converting low‐energy red‐light excitation into chemically responsive electronic function remains challenging. Here we show that squaraine‐sensitized TiO2 domains embedded in single‐walled carbon nanotube networks generate a red‐light‐gated charge‐transfer state that reacts with O2 ...

Electron Bridge Enhanced Charge Polarization Enables Efficient and Ultra‐Long Stable Urea Electrosynthesis

Angewandte Chemie, EarlyView.
An electron bridge strategy is developed to regulate charge polarization in Pd1 and Ni1 dual single‐atom sites, promoting CO2 reduction, nitrate reduction, and C–N coupling simultaneously. The resulting catalyst achieves efficient urea electrosynthesis with high activity and record durability over 1700 h.

Suppressing Cathode Corrosion Induced by Impurity Cations in Alkaline Water Electrolyzers

Angewandte Chemie, EarlyView.
Impurity Fe species in electrolyte accelerate cathodic corrosion in alkaline electrolyzers by promoting peroxide formation. A strongly Lewis acidic CeOx protection layer stabilizes interfacial electronic structure via Fe−CeOx interactions, scavenges reactive oxygen species, and suppresses Fe accumulation, enabling stable Ni cathodes under universal ...

Lattice Nitrogen Couples Cuδ+ Stabilization With Pathway Control for CO2‐to‐Methanol Electroreduction

Angewandte Chemie, EarlyView.
Lattice‐incorporated nitrogen regulates amorphous CuO by forming a resilient Cu─N/O coordination environment that suppresses excessive Cu reduction and preserves Cuδ+ sites under reducing conditions. The resulting catalyst enables selective CO2‐to‐methanol conversion, achieving a methanol Faradaic efficiency of 48% in an H‐type cell and a methanol ...
