The Sr-doped perovskite oxides La_1-xSr_xCoO₃ (x=0, 0.2, 0.4, 0.6, 0.8), as the electrocatalyst for bi-functional oxygen electrode, were synthesized by sol-gel method. The test results show that Sr-doped La_1-xSr_xCoO₃ has higher electrocatalytic activities than LaCoO₃. In addition, La_0.6Sr_0.4CoO₃ reveal excellent catalytic activity for the oxygen evolution reaction and oxygen reduction reaction, reaching a maximum of 0.244 A·cm^-2 (at -0.6 V vs Hg/HgO) and 0.303 A·cm^-2 (at 1 V vs Hg/HgO). In order to further improve the catalytic activity of the catalyst, α-MnO₂ nano-wires as bi-functional catalyst was prepared by hydrothermal synthesis and added into the La_0.6Sr_0.4CoO₃. The activities of bi-functional catalysts of α-MnO₂/La_0.6Sr_0.4CoO₃ were markedly superior compared with α-MnO₂ or La_0.6Sr_0.4CoO₃ perovskite oxide when the mass fraction of 40% α-MnO₂, demonstrating a synergistic effect, which was responsible for the improvement of electrochemical catalytic activity and stability of the bi-functional oxygen electrode.
