| 挥发性有机化合物(VOCs)对环境的严重污染和对人体的危害引起了人们的重视。冷等离子体与催化剂耦合形成的协同效应可显著提高VOCs低温转化速率，减少二次污染和降低能耗，具有较好的应用前景。协同催化效果主要取决于催化剂物化性能，可通过调控催化剂的组成、粒径和结构改善协同催化活性。锰基氧化物因其具有较高的储氧能力、稳定的晶体结构、较好的氧气活化性能和良好的抗中毒能力等优点而被广泛应用于冷等离子体协同催化净化VOCs的应用研究。通过金属离子掺杂调控锰基氧化物的离子价态、氧迁移率和氧气吸附量，是改善催化剂与等离子体协同催化性能主要方法。本文总结了近年来锰基氧化物与冷等离子体协同催化氧化VOCs的研究进展，主要包括氧化锰晶型、分散度和掺杂金属离子对协同催化氧化VOCs的活性影响趋势及反应机理。分析冷等离子体与锰基氧化物催化剂协同氧化VOCs中存在的问题并对其发展前景进行了展望。 |
| 英文摘要: |
| Volatile organic compounds (VOCs) have drawn attention to the serious pollution of the environment and the harm to human beings. The synergistic effect formed by the coupling of cold plasma and catalyst can significantly improve the low temperature conversion rate of VOCs, reduce secondary pollution and reduce energy consumption, which has a good application prospect. The synergistic catalytic effect can be improved by adjusting the composition, particle size and structure of the catalyst. Due to the advantages of high oxygen storage capacity, stable crystal structure and good oxidation performance, the combination of manganese-based oxides and cold plasma for the catalytic oxidation of VOCs has been widely studied. The main method to improve the synergistic catalytic performance of the catalyst and plasma hybrid is to tune the ion valence state, oxygen mobility and oxygen adsorption capacity of the manganese oxide by metal ion doping. In this paper, the synergistic catalytic performance and mechanism of cold plasma and manganese-based oxide catalysts hybrid for VOCs oxidation were reviewed, and the suggestions for the study of synergistic mechanism and catalysts were proposed. |
