| contents | Fluorine‐Induced Synergistic Surface Reconstruction and LOM Activation in FeVO 4 for Enhanced Water Oxidation Xiaogang Liu Mengyu Chen Shuangying Li Wei Wang ChemSusChem The development of highly efficient oxygen evolution reaction (OER) catalysts, considering both structural reconstruction and reaction mechanism, is of paramount importance for electrochemical water splitting. Herein, we demonstrate a substantial improvement in the OER performance of iron vanadate (FeVO 4 ) nanorods achieved through the fluorine‐anion occupancy of oxygen vacancies. The structural modification markedly enhances metal–oxygen covalency, thereby facilitating rapid charge transfer at the catalyst‐electrolyte interface and optimizing the dissolution kinetics of vanadium species. Importantly, the accumulation of charge density at lattice oxygen sites activates the lattice oxygen‐mediated (LOM) pathway, thereby promoting the efficient incorporation of OH − ions and triggering in situ surface reconstruction into catalytically active FeOOH phases during operation. The synergistic effects of LOM activation and favorable surface reconstruction collectively result in enhanced electrochemical activity and improved operational stability. This study successfully illustrates a novel and intriguing concept for regulating local lattice oxygen activity for the development of high‐performance OER electrocatalysts. 10.1002/cssc.70747 http://onlinelibrary.wiley.com/termsAndConditions#vor |
