Unlocking Superior Stability in High‑Salinity Oxygen Evolution Reaction: A Ru Stabilized NiFeOOH/Ni Anode with over 2000 h Durability

Caption

  • A dual-function stabilizing agent in NiFe-based anodes is proposed.
  • Ru incorporation promotes the formation of a protective surface layer enriched with Ru atoms, along with a denser NiFeOOH catalyst structure.
  • RuSA-NiFeOOH/Ni anode exhibits exceptional operational stability over 2000 h at an industrial current density of 0.5 A cm−2 in a chloride-enriched alkaline medium.
