審稿意見說重新英文摘要翻譯，并注意介詞應(yīng)用~ 摘要：采用檸檬酸絡(luò)合法制備LaMnO3和La0.8K0.2MnO3鈣鈦礦催化劑，運(yùn)用程序升溫氧化（TPO）考察在不同反應(yīng)氣氛下催化燃燒碳煙的活性，并通過XRD、O2-TPD、NO-TPD、XPS以及NO預(yù)處理后O2-TPD等技術(shù)對(duì)催化劑進(jìn)行表征和分析。結(jié)果表明：活性氧含量與碳煙的深度氧化密切相關(guān)。NO除了部分氧化形成NO2以外，還促進(jìn)了活性氧物種的生成。由于La0.8K0.2MnO3比LaMnO3有更多的氧空位，利于氧的活化和遷移，所以NO對(duì)于La0.8K0.2MnO3催化碳煙的作用更為顯著。 |

供參考： Abstract: Perovskite catalysts LaMnO3 and La0.8K0.2MnO3 were prepared using the citric acid complex method, and temperature programmed oxidation (TPO) was employed to investigate the activity of the catalytic combustion of soot under different reaction conditions. After XRD, O2-TPD of NO-TPD, XPS, and NO pretreatment, the catalysts were characterized and analyzed by O2-TPD and other techniques. The results showed that the deep oxidation of soot was closely related to the active oxygen content. Apart from being partially oxidized into NO2, the NO also promoted the generation of reactive oxygen species. Compared with LaMnO3, La0.8K0.2MnO3 had more oxygen vacancies which were conducive to oxygen activation and migration. Therefore, NO played a more significant role in the catalysis of soot by La0.8K0.2MnO3. |
