It was shown that the perovskite lattice became more and more distorted when lowering the size of the A-site cation. The manganite-based perovskites were evaluated for the ability to electrochemically reduce oxygen and nitric oxide in the temperature range of 200 to 400°C. At the lowest temperature, the electrodes were better at reducing nitric oxide than oxygen. At higher temperatures, the activity for the reduction of oxygen and nitric oxide became similar. The activation energies for the reduction of oxygen and nitric oxide were markedly different for LaMnO_{3+ δ}和PrMnO_{3+ δ}而它是SmMnO相似_{3+ δ}和GdMnO_{3+ δ}。SN - 2090-3529 UR - https://doi.org/10.1155/2020/4013697 DO - 10.1155 /四百○一万三千六百九十七分之二千○二十〇JF - 国际期刊电化学PB的 - Hindawi出版KW - ER -
