Oxygen-Bonding State and Oxygen-Reduction Reaction Mechanism of Pr<sub>0.7</sub>Ca<sub>0.3</sub>Mn<sub>1−x</sub>Co<sub>x</sub>O<sub>3−d</sub> (x = 0, 0.1, 0.2, 0.3)

Oxygen-Bonding State and Oxygen-Reduction Reaction Mechanism of Pr<sub>0.7</sub>Ca<sub>0.3</sub>Mn<sub>1−x</sub>Co<sub>x</sub>O<sub>3−d</sub> (x = 0, 0.1, 0.2, 0.3)

We investigated the effects of Co doping on Pr<sub>0.7</sub>Ca<sub>0.3</sub>MnO<sub>3−d</sub> in the perspective of an oxygen-bonding state change. In all compositions, Pr<sub>0.7</sub>Ca<sub>0.3</sub>Mn<sub>1−x</sub>Co<sub&g...
