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

Advanced 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).

Electrocatalytic Urea Synthesis From CO2 and N2/NO3−: Bridging Catalyst Activity, C–N Coupling Kinetics, and Industrial Applicability

Advanced Science, EarlyView.
This review compares NO3− + CO2 and N2 + CO2 electrocatalytic urea synthesis in feedstock properties, catalyst design, C–N coupling mechanisms, performance optimization, and engineering applicability. The two systems correspond to a near‐term deployable route and a long‐term green synthesis goal, respectively.

Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.
