摘要	The anode activity can to a great degree limit the cathodic hydrogen evolution efficiency in an electrolyte cell. Thus, cost-efficient electrocatalysts with good water oxidation performance and stability are highly desired in widespread implementation of the hydrogen production from water splitting. This paper proposes a facile corrosion-reconstruction strategy to transform Fe surface into a Fe-Co hydroxide layer to improve the oxygen evolution activity. The as-prepared catalyst was measured to have an over-potentential as low as 320 mV at 100 mA·cm, and its stability even exceeded 600 h. Surface and Raman spectroscopy analyses indicated that the catalyst experienced chemical changes from hydroxides to oxyhydroxides and Co to Co during oxygen evolution reaction (OER). The corrosion-reconstruction is not only an economical method to synthesize a highly efficient, stable and durable Fe-based catalysts, it also converses the detrimental corrosion into a beneficial catalyst fabrication process.
