The synthesized CeO<jats:sub>2<\/jats:sub>@[BMIm][HCO<jats:sub>3<\/jats:sub>] catalyst having high thermal stability harnesses the unique physicochemical properties of CeO<jats:sub>2<\/jats:sub> and the ionic liquid to exhibit a DMC yield of 10.4\u2009% and a methanol conversion of 16.1\u2009% at optimal conditions (pressure of CO<jats:sub>2<\/jats:sub>=5\u2005MPa; temperature=130\u2009\u00b0C). The catalytic behavior of CeO<jats:sub>2<\/jats:sub>@[BMIm][HCO<jats:sub>3<\/jats:sub>] studied with a detailed XRD, XPS, CO<jats:sub>2<\/jats:sub> and NH<jats:sub>3<\/jats:sub>\u2010TPD, Raman spectroscopy, TGA, FTIR, SEM and TEM suggests that the synergy between the two catalytic components originating from an increased surface oxygen vacancies boosts the overall catalytic performance. After several recycling tests, the catalyst demonstrated no significant reduction in DMC yield and methanol conversion. This platform is an attractive approach to synthesize thermally stable nanoparticle@ionic liquid that retains and merges the physical attributes of both materials for producing useful bulk chemicals from readily available chemical resources.<\/jats:p>","DOI":"10.1002\/cssc.202301805","type":"journal-article","created":{"date-parts":[[2024,2,15]],"date-time":"2024-02-15T22:43:06Z","timestamp":1708036986000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Boosting Dimethyl Carbonate Production from CO<sub>2<\/sub> and Methanol using Ceria\u2010Ionic Liquid Catalyst"],"prefix":"10.1002","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9805-663X","authenticated-orcid":false,"given":"Bernard Baffour","family":"Asare\u2010Bediako","sequence":"first","affiliation":[{"name":"Center for Renewable Carbon University of Tennessee  2506 Jacob Drive 37996 Knoxville TN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7523-1266","authenticated-orcid":false,"given":"Mi","family":"Li","sequence":"additional","affiliation":[{"name":"Center for Renewable Carbon University of Tennessee  2506 Jacob Drive 37996 Knoxville TN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-8777-4686","authenticated-orcid":false,"given":"Austin","family":"Houston","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering University of Tennessee  2506 Jacob Drive 37996 Knoxville TN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3872-8828","authenticated-orcid":false,"given":"Paolo","family":"Vilmercati","sequence":"additional","affiliation":[{"name":"Department of Physics and Astronomy The University of Tennessee Knoxville  1408 Circle Drive 37996 Knoxville TN USA"},{"name":"Institute for Advanced Materials and Manufacturing  2641 Osprey Vista Way 37920 Knoxville TN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3490-6041","authenticated-orcid":false,"given":"Norman","family":"Mannella","sequence":"additional","affiliation":[{"name":"Department of Physics and Astronomy The University of Tennessee Knoxville  1408 Circle Drive 37996 Knoxville TN USA"},{"name":"Institute for Advanced Materials and Manufacturing  2641 Osprey Vista Way 37920 Knoxville TN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2117-4259","authenticated-orcid":false,"given":"Nicole","family":"Labb\u00e9","sequence":"additional","affiliation":[{"name":"Center for Renewable Carbon University of Tennessee  2506 Jacob Drive 37996 Knoxville TN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6586-5919","authenticated-orcid":false,"given":"Nourredine","family":"Abdoulmoumine","sequence":"additional","affiliation":[{"name":"Center for Renewable Carbon University of Tennessee  2506 Jacob Drive 37996 Knoxville TN USA"},{"name":"Department of Biosystems Engineering and Soil Science University of Tennessee  2506 E.J.
