Abstract Seawater electrolysis is an attractive way of making H 2 in coastal areas, and NiFe‐based materials are among the top options for alkaline seawater oxidation (ASO). However, ample Cl − can severely corrode catalytic sites lead to limited lifespans.

In situ/ex studies show spontaneous, timely, appropriate COST safeguards active against attack during ASO even at ampere‐level current density ( j ). Our catalyst shows efficient stable performance, which requires overpotential as low 349 mV attain 1 A cm −2 . Moreover, with protective surface CO 3 2− exhibits slight activity degradation after 600 h under seawater. This work reports effective design concepts level self‐transformation, acting momentous step toward defending seawater‐to‐H conversion systems.
