Abstract The development of robust and efficient electrocatalysts for the oxygen evolution reaction (OER) has been main focus water electrolysis but remains a great challenge. Here, synthesis highly active ultra‐stable Fe‐CoOOH electrocatalyst is reported by steering raw cobalt foam via an in situ solution combustion method assisted galvanic replacement subsequent electrochemical reconstruction CoFeO x pre‐catalyst. In/ ex analysis physicochemical characterizations show that undergoes quick chemical slow morphological to nanosheets. possesses semi‐crystalline nature with distinct short‐range ordering outstanding OER activity overpotentials as low 271 291 mV at current densities 500 1,000 mA cm −2 , respectively. remarkable stability under least 700 h achieved. Theoretical calculations confirm crucial role Fe doping facilitating surface reconstruction, enhancing activity, improving Fe‐CoOOH. Comparative other transition metals reveals unique ability adsorb onto CoOOH surface, thereby modulating electronic density faster adsorption intermediates. This work represents valuable insights into processes.
