Herein, CeO2 modification was employed to regulate the effect of the interaction between Al2O3 and SiC on the Ni\/Al2O3\/SiC structured catalyst for CO2 methanation. The results of characterization and catalytic performance tests reveal that CeO2 promotes the formation of Ni-Ce interaction, which induces the generation of abundant oxygen vacancies and weakens the Al-mediated constraint on Ni reducibility due to Ni-Al2O3 interaction, thereby significantly boosting both activity and stability. Therefore, the optimal Ni-16CeO2\/Al2O3\/SiC catalyst exhibits a much higher CO2 conversion at 300\u2013400 \u00b0C and superior stability during an 80 h long-term test in comparison with the Ni\/Al2O3\/SiC catalyst. This work provides a feasible strategy for designing a high-performance structured catalyst for CO2 methanation.<\/jats:p>","DOI":"10.3390\/ma19122612","type":"journal-article","created":{"date-parts":[[2026,6,17]],"date-time":"2026-06-17T15:11:22Z","timestamp":1781709082000},"page":"2612","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["CeO2 Induced Ni-Ce Interaction Enables Efficient CO2 Methanation on Ni\/Al2O3\/SiC Structured Catalyst"],"prefix":"10.3390","volume":"19","author":[{"given":"Jiyue","family":"Xu","sequence":"first","affiliation":[{"name":"School of Environmental Science and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1423-9664","authenticated-orcid":false,"given":"Jiaxin","family":"Qian","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangli","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fei","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Nanjing Tech University, Nanjing 211816, China"},{"name":"State Key Laboratory of Materials-Oriented Chemical Engineering, National Engineering Research Center for Special Separation Membrane, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yiqing","family":"Zeng","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Nanjing Tech University, Nanjing 211816, China"},{"name":"State Key Laboratory of Materials-Oriented Chemical Engineering, National Engineering Research Center for Special Separation Membrane, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shule","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaoxiang","family":"Zhong","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Nanjing Tech University, Nanjing 211816, China"},{"name":"State Key Laboratory of Materials-Oriented Chemical Engineering, National Engineering Research Center for Special Separation Membrane, Nanjing Tech University, Nanjing 211816, China"},{"name":"NJTECH University Suzhou Future Membrane Technology Innovation Center, Suzhou 215300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.1039\/c3ee00056g","article-title":"Catalysis for CO2 conversion: A key technology for rapid introduction of renewable energy in the value chain of chemical industries","volume":"6","author":"Centi","year":"2013","journal-title":"Energy Environ.
