Abstract
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<sub>7</sub> O<sub>12</sub> and LaMn<sub>7</sub> O<sub>12</sub> 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<sub>4</sub> and octahedral MnO<sub>6</sub> units to promote direct OO bond formations.
