Abstract
AbstractDevelopment of high‐efficiency and robust multi‐element transition metal oxides for oxygen evolution reaction (OER) is crucial to improve the energy efficiency of electrocatalytic water splitting. Here, we report a simple and efficient sol‐gel strategy to synthesize an amorphous ternary Fe−Co−Ga oxide composite with high OER activity, low Tafel slope, and good durability. The overpotential at 10 mA ⋅ cm−2 of the FeCoGaOx on glassy carbon, platinum, carbon paper, and nickel foam electrode is 245, 275, 237, and 215 mV, respectively, in an alkaline electrolyte. The addition of gallium into the FeCoOx system significantly promotes the charge transfer kinetics, thus improving the OER activity. This work affords a controllable method to vastly prepare cost‐effective and high‐efficiency multi‐metal water oxidation electrocatalysts.
