%X 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.
