摘要：采用柠檬酸络合法制备LaMnO3和La0.8K0.2MnO3钙钛矿催化剂，运用程序升温氧化（TPO）考察在不同反应气氛下催化燃烧碳烟的活性，并通过XRD、O2-TPD、NO-TPD、XPS以及NO预处理后O2-TPD等技术对催化剂进行表征和分析。结果表明：NO的存在促进了碳烟的催化氧化，但是对LaMnO3和La0.8K0.2MnO3氧化碳烟的促进效果不同。这与催化剂表面氧空位和活性氧物种有密切联系。 关键词：一氧化氮；钙钛矿催化剂；活性氧物种；碳烟燃烧 我的翻译是： Abstract: La0.8MnO3 and La0.8K0.2MnO3 perovskite-type catalysts were prepared using the citric acid sol-gel method. TPO tests were performed to evaluate the catalyst activity for soot oxidation in different gas atmosphere. Catalysts were characterized and analyzed with XRD、O2-TPD、NO-TPD、XPS and NO pretreated O2-TPD. The results showed that the presence of NO had a positive effect on the catalytic oxidation of soot, but as to LaMnO3 and La0.8K0.2MnO3 the promoting effect was in different degree in the catalytic oxidation of soot .It was closely associated with the surface vacancy oxygen and the active oxygen species on the catalysts. |

Abstract: La0.8MnO3 and La0.8K0.2MnO3 perovskite-type catalysts were prepared using the citric acid sol-gel method. TPO tests were performed to evaluate the catalyst activity for soot oxidation in different gas atmosphere. Catalysts were characterized and analyzed with XRD, O2-TPD, NO-TPD, XPS and NO pretreated O2-TPD. The results showed that the presence of NO had a positive effect on the catalytic oxidation of soot. Moreover, for LaMnO3 and La0.8K0.2MnO3, the promoting effect was different in the catalytic oxidation of soot. It was closely related to the surface vacancy oxygen and the active oxygen species of the catalysts. 顿号，转折，还有几个小地方。 |
