a–c LSV curves (a), Tafel slope (b) and EIS Nyquist plots (c) of RhRu3Ox, Hom-RuO2 and Com-RuO2. The solution resistance was determined from the intersection of the EIS curve with the real axis when the imaginary part (Z″) equals zero, yielding a value of 25.0 ± 0.4 Ω. d Cdl plots calculated from CV curves. e Tafel plots of RhRu3Ox at different temperatures. f Arrhenius plot of OER exchange current density of RhRu3Ox and Hom-RuO2. g Stability tests of RhRu3Ox, Hom-RuO2 and Com-RuO2. All the error bars mentioned above represent the standard deviations of 3 independent experimental data.
