Synthesizing oxygen evolution reaction (OER) catalysts with enhanced activity by codoping has been proven to be a feasible approach for the efficient use of noble metals via renewing their basic intrinsic properties. In continuation of the research in codoping, we prepare a ruthenium-based bimetallic doped catalyst MnxFeyRu1-x-yO2 with an outstanding OER activity as compared to pure RuO2, one of the state-of-the-art OER catalysts. The synthesized codoped RuO2 with a Mn/Fe molar ratio of 1 reflected a Tafel slope of only 41 mV dec(-1), which is appreciably lower than 64 mV dec(-1) for pure RuO2. The X-ray photoelectron spectroscopy (XPS) performed reveals that oxygen vacancy and manganese valency are the key factors of the OER activity for codoped catalysts.
