In continuation of the research in codoping, we prepare a ruthenium-based bimetallic doped catalyst MnxFeyRu1–xyO2 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. %I ACS Publications
