In order to enhance the catalytic activity of LaMnO₃ perovskite catalyst and induce a regenerative property under repeated reducing-oxidizing (redox) reaction conditions, a new LaMnCu_0.1O₃ perovskite is developed for oxidation of the simulated exhaust gas. Addition of Cu to LaMnO₃ significantly enhances the specific surface area, reducibility and surface oxygen mobility of LaMnCu_0.1O₃, which result in the high oxidation activity of this catalyst. During the redox fluctuations using LaMnCu_0.1O₃, the enhancements of up to 13.4 % and 10.7 % are observed in CO and C₃H₈ conversions, respectively. X-ray photoelectron spectroscopy (XPS) analysis clarify that Cu reversibly reduces to Cu¹⁺ and Cu° in the reducing atmosphere and re-oxidizes to Cu²⁺ in the oxidizing atmosphere. The activity enhancement is finally concluded to be due entirely to the formation of Cu¹⁺ species during the reduction period. Therefore, the repeatable activity enhancement and regeneration of LaMnCu_0.1O₃ offer it as an “intelligent” and stable catalyst.

为了增强LaMnO ₃钙钛矿催化剂的催化活性并在重复的还原-氧化（氧化还原）反应条件下诱导再生性能，开发了一种新的LaMnCu _0.1 O ₃钙钛矿用于氧化模拟废气。向LaMnO _3中添加Cu显着提高了LaMnCu _0.1 O ₃的比表面积，还原性和表面氧迁移率，这导致该催化剂的高氧化活性。在使用LaMnCu _0.1 O ₃的氧化还原波动期间，在CO和C ₃ H ₈中观察到高达13.4％和10.7％的增强。转换。X射线光电子能谱（XPS）分析表明，Cu在还原性气氛中可逆地还原为Cu ¹⁺和Cu°，在氧化性气氛中再氧化为Cu ²⁺。最终得出的活性增强完全归因于还原期间Cu ¹⁺物种的形成。因此，LaMnCu _0.1 O ₃可重复的活性增强和再生提供了它作为“智能”且稳定的催化剂。
