Tuning the Electronic Structure and Spin State of Fe─N─C Catalysts Using an Axial Oxygen Ligand and Fe Clusters for High‐Efficiency Rechargeable Zinc–Air Batteries

Advanced Functional Materials, EarlyView.
A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Modulating Surface‐Active Hydrogen for Facilitating Nitrate‐to‐Ammonia Electroreduction on Layered Double Hydroxides Nanosheets

Advanced Functional Materials, EarlyView.
The NiCuFe‐layered double hydroxides nanosheets are synthesized for facilitating nitrate‐to‐ammonia with a high ammonia yield of 1.64 mmol h−1 cm−2, Faradaic efficiency of 94.8% and stability for 15 cycles. The assembled Zn‐nitrate battery delivers a remarkable power density of 12.4 mW cm−2.

Atomically Revealing Bulk Point Defect Dynamics in Hydrogen‐Driven γ‐Fe2O3 → Fe3O4 → FeO Transformation

Advanced Functional Materials, EarlyView.
In situ TEM uncovers the atomic‐scale mechanisms underlying hydrogen‐driven γ‐Fe2O3→Fe3O4→FeO reduction. In γ‐Fe2O3, oxygen vacancies cluster around intrinsic Fe vacancies, leading to nanopore formation, whereas in Fe3O4, vacancy aggregation is suppressed, preserving a dense structure.
