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

<div>At 400 C, the voltammograms recorded on the four manganite-based perovskites in 1% NO in Ar are becoming more similar. The voltammograms are recorded with a sweep rate of 1 mV/s. It is noteworthy that the downward bend of the voltammograms recorded on the SmMnO<sub>3+<i>δ</i></sub> and GdMnO<sub>3+<i>δ</i></sub> perovskites at low potentials is more pronounced than that on the LaMnO<sub>3+<i>δ</i></sub> and PrMnO<sub>3+<i>δ</i></sub> perovskites.</div>
