Overcoming the *H‐NOx Coupling Bottleneck via Palladium‐Enabled Relay Catalysis on CuCo2O4 Toward Ampere‐Level Nitrate‐to‐Ammonia

open access: yesAdvanced Science, EarlyView.
Pd‐doped hollow spiny CuCo2O4 microspheres deliver ampere‐level electrocatalytic nitrate to ammonia. Cu and Co sites undergo relay catalysis for sequential nitrate reduction, while Pd accelerates water dissociation to supply abundant active hydrogen (*H).

Anchoring Pd Single Atoms on N‐Doped MOF‐Derived TiO2 for Photocatalytic Hydrogen Evolution With an Ultra‐High Rate up to 185.8 mmol g−1 h−1

open access: yesAdvanced Science, EarlyView.
N doping is adopted to introduce abundant binding sites within TiO2 matrix, which enables firm immobilization of isolated Pd single atoms. The as‐constructed PdN‐TiO2 single atom photocatalyst achieves greatly promoted solar‐driven hydrogen evolution performance.

Coupling Fast Zn2+ Kinetics With V–O Framework Stabilization via Nitrogen‐Rich Interfacial Engineering of Spinel ZnV2O4

open access: yesAdvanced Science, EarlyView.
Graphitic carbon nitride acts as a nitrogen‐rich interfacial regulator for spinel ZnV2O4 cathodes in aqueous zinc‐ion batteries. Polar N sites promote interfacial Zn2+ adsorption, migration, and charge transfer, while mitigating local framework distortion and reinforcing V─O bonding.

Post‐Synthetic Cerium Modification of Commercial NCM811 for Concurrent Cycling and Safety Upgrading

open access: yesAdvanced Science, EarlyView.
Cerium ion doping and CeO2 coating work synergistically to reinforce commercial NCM811 cathodes. This strategy stabilizes the lattice and strengthens the interface against degradation and side reactions. The modified cathode shows enhanced rate capability and cycling stability.
