CoFe-based catalysts have shown excellent activity for the oxygen evolution reaction (OER), with oxidation states of active sites playing a crucial role in determining catalytic performance. However, how to effectively increase state these remains key challenge. In this work, facile treatment NaBH4 solution was employed modulate surface CoFeOxHy catalysts, inducing an enhanced OER activity. The overpotential at 10 mA cm−2 NaBH4-treated CoFe catalyst reduced 270 mV, indicating improved X-ray diffraction (XRD), Raman spectroscopy, and photoelectron spectroscopy (XPS) results reveal that induced phase reconstruction oxalate framework, critical step enhancing its properties. strong reducing ability strengthened Co-Fe interaction, allowing retention low-valence Co species while facilitating formation high-valence Fe sites. This dual modulation significantly accelerated charge transfer kinetics, ultimately boosting These findings highlight importance improving providing insights developing efficient electrochemical water splitting.
