Bifunctional electrocatalysts for oxygen evolution/reduction reaction (OER/ORR) are desirable for the development of energy conversion technologies. It is discovered that the manganese quadruple perovskites CaMn O and LaMn O show bifunctional catalysis in the OER/ORR. A possible origin of the high OER activity is the unique surface structure through corner-shared planar MnO and octahedral MnO units to promote direct OO bond formations.
双功能电催化剂对于析氧/氧还原反应（OER/ORR）的发展是非常理想的。研究发现，锰的四重钙钛矿 CaMn O 和 LaMn O 在 OER/ORR 中表现出双功能催化作用。高 OER 活性的一个可能起源是通过共享角的平面 MnO 和八面体 MnO 单元的独特表面结构促进直接 OO 键的形成。
