Abstract Seawater electrolysis under alkaline conditions is a crucial technology for sustainable hydrogen production. However, achieving the long‐term stability of electrocatalyst remains significant challenge. In this study, it demonstrated that surface reconstruction transition metal nitride (TMN) can be used to develop highly stable oxygen evolution reaction (OER) electrocatalyst. Rapid introduction phosphate groups (PO 4 3− ) accelerates in situ Ni 3 FeN, generating catalyst, with conductive core and Cl − ‐resistant hydroxide shell demonstrates outstanding performance, maintaining over 2500 h at 1 A cm −2 current density seawater. characterization functional theory (DFT) calculations reveal dynamic active sites, providing insights into mechanisms driving stability. This work not only introduces an efficient approach TMN‐based catalyst design but also advances development durable electrocatalysts industrial‐scale seawater
