Electrochemical Reduction of Oxygen and Nitric Oxide on Mn-Based Perovskites with Different A-Site Cations

<div>Four voltammograms recorded at 300 C in 10% O<sub>2</sub> in Ar with a sweep rate of 1 mV/s. Again a marked difference is seen as a function of the A-site cation. The LaMnO<sub>3+<i>δ</i></sub> perovskite is the most active compound for both oxygen evolution and oxygen reduction, whereas the PrMnO<sub>3+<i>δ</i></sub> perovskite is the one with the lowest activity.</div>
