Non-precious metal bifunctional catalysts are of great interest for metal-air batteries, electrolysis, and regenerative fuel cell systems due to their performance and cost benefits compared to the Pt group metals (PGM). In this work, metal oxides of La 0.1 Ca 0.9 MnO 3 and nano Co 3 O 47 catalyst as bifunctional catalysts were used in oxygen reduction and evolution reactions (ORER). The catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N 2 adsorption isotherms. The electrocatalytic activity of the perovskite-type La 0.1 Ca 0.9 MnO 3 and Co 3 O 4 catalysts both as single and mixtures of both were assessed in alkaline solutions at room temperature. Electrocatalyst activity, stability, and electrode kinetics were studied using cyclic voltammetry (CV) and rotating disk electrode (RDE). This study shows that the bifunctional performance of the mixed La 0.1 Ca 0.9 MnO 3 and nano Co 3 O 4 was superior in comparison to either La 0.1 Ca 0.9 MnO 3 or nano Co 3 O 4 alone for ORER. The improved activity is due to the synergistic effect between the La 0.1 Ca 0.9 MnO 3 and nano Co 3 O 4 structural and surface properties. This work illustrates that hybridization between these two metal oxides results in the excellent bifunctional oxygen redox activity, stability, and cyclability, leading to a cost-effective application in energy conversion and storage, albeit to the cost of higher catalyst loadings.
