f‐p‐d Gradient Orbital Coupling Induced Spin State Enhancement of Atomic Fe Sites for Efficient and Stable Oxygen Reduction Reaction

Advanced Functional Materials, EarlyView.
The f‐p‐d (Eu─O─Fe) gradient orbital coupling induces electron delocalization and the introduced f‐band of Eu shifts the spin state of the Fe center in FePc from low‐spin to intermediate‐spin. This strategy simultaneously enhances oxygen reduction reaction (ORR) activity, reaction kinetics, and stability, resulting in superior ORR performance and ...

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous
