In this study, MnCexOy was consciously synthesized by \u03b1-MnO2 doped with Ce3+ (Ce:Mn = 1:10) and employed as the ozonation catalyst for quinoline degradation. After that, the removal efficiency and mechanism of quinoline were systematically analyzed by characterizing the physicochemical properties of MnCexOy, investigating free radicals and monitoring the solution pH. Results indicated that the removal rate of quinoline was greatly improved by the prepared MnCexOy catalyst. Specifically, the removal efficiencies of quinoline could be 93.73, 62.57 and 43.76%, corresponding to MnCexOy, \u03b1-MnO2 and single ozonation systems, respectively. The radical scavenging tests demonstrated that \u2022OH and \u2022O2- were the dominant reactive oxygen species in the MnCexOy ozonation system. Meanwhile, the contribution levels of \u2022OH and \u2022O2- to quinoline degradation were about 42 and 35%, respectively. The abundant surface hydroxyl groups and oxygen vacancies of the MnCexOy catalyst were two important factors for decomposing molecular O3 into more \u2022OH and \u2022O2-. This study could provide scientific support for the application of the MnCexOy\/O3 system in degrading quinoline in bio-treated coking wastewater.<\/jats:p>","DOI":"10.2166\/wst.2024.027","type":"journal-article","created":{"date-parts":[[2024,1,29]],"date-time":"2024-01-29T18:19:48Z","timestamp":1706552388000},"page":"823-837","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":11,"title":["Effective degradation of quinoline by catalytic ozonation with MnCe<i>x<\/i>O<i>y<\/i> catalysts: performance and mechanism"],"prefix":"10.2166","volume":"89","author":[{"given":"Jie","family":"Zhang","sequence":"first","affiliation":[{"name":"a School of Environment Science and Spatial Informatics, China University of Mining and Technology, Xuzhou, 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaochang","family":"Wu","sequence":"additional","affiliation":[{"name":"a School of Environment Science and Spatial Informatics, China University of Mining and Technology, Xuzhou, 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ben","family":"Dong","sequence":"additional","affiliation":[{"name":"b Jiangsu Fangzheng Environmental Protection Consulting (Group) Co., Ltd, Xuzhou, 221132, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sijie","family":"Ge","sequence":"additional","affiliation":[{"name":"a School of Environment Science and Spatial Informatics, China University of Mining and Technology, Xuzhou, 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5645-0295","authenticated-orcid":false,"given":"Shilong","family":"He","sequence":"additional","affiliation":[{"name":"a School of Environment Science and Spatial Informatics, China University of Mining and Technology, Xuzhou, 221116, Jiangsu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2024,1,29]]},"reference":[{"key":"2024021606091805600_WST-D-23-01157C1","doi-asserted-by":"crossref","first-page":"129047","DOI":"10.1016\/j.chemosphere.2020.129047","article-title":"Catalytic ozonation of norfloxacin using CO3O4\/C composite derived from ZIF-67 as catalyst","volume":"265","year":"2021","journal-title":"Chemosphere"},{"issue":"8","key":"2024021606091805600_WST-D-23-01157C2","doi-asserted-by":"crossref","first-page":"104983","DOI":"10.1016\/j.arabjc.2023.104983","article-title":"Enhanced degradation of quinoline in three-dimensional electro-Fenton system through NiCo2S4\/g-C3N4 particles","volume":"16","year":"2023","journal-title":"Arabian J.
