In this study, we synthesized selenium vacancy-rich iron selenide (Fe(3)Se(4)) through an electro-precipitation method. Combined theoretical calculations and experimental characterization confirm that these selenium vacancies serve as highly efficient active sites, effectively modulating the local electronic structure of Fe centers and optimizing their adsorption behavior toward reaction intermediates. In the oxygen evolution reaction (OER), this defective structure significantly enhances water molecule adsorption and dissociation while minimizing the activation energy barrier of the rate-determining step. Benefiting from these features, the Se-deficient Fe(3)Se(4) catalyst exhibits high OER performance, requiring only 274.8 mV overpotential to achieve 50 mA cm(-2) while demonstrating remarkable stability for 100 h at 100 mA cm(-2), highlighting its rapid OER kinetics.
