However, they are rarely used in combined CO<jats:sub>2<\/jats:sub> capture and conversion processes. Utilizing imidazolium\u2010based ionic liquids, the conversion of CO<jats:sub>2<\/jats:sub> to methanol was greatly improved in polyamine assisted systems catalyzed by homogeneous pincer catalysts with Ru and Mn metal centers. Among the ionic liquids tested, [BMIM]OAc was found to perform the best under the given reaction conditions. Among the polyamine tested, pentaethylenehexamine (PEHA) led to the highest conversion rates. Ru\u2010Macho and Ru\u2010Macho\u2010BH were the most active catalysts. Direct air capture utilizing PEHA as the capture material was also demonstrated and produced an 86\u2009% conversion of the captured CO<jats:sub>2<\/jats:sub> to methanol in the presence of [BMIM]OAc.<\/jats:p>","DOI":"10.1002\/cssc.202301789","type":"journal-article","created":{"date-parts":[[2024,4,9]],"date-time":"2024-04-09T22:22:02Z","timestamp":1712701322000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Addition of Imidazolium\u2010Based Ionic Liquid to Improve Methanol Production in Polyamine\u2010Assisted CO<sub>2<\/sub> Capture and Conversion Systems Using Pincer Catalysts"],"prefix":"10.1002","volume":"17","author":[{"given":"Christopher J.","family":"Koch","sequence":"first","affiliation":[{"name":"Loker Hydrocarbon Research Institute and Department of Chemistry University of Southern California  837 Bloom Walk Los Angeles CA 90089-1661 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alain","family":"Goeppert","sequence":"additional","affiliation":[{"name":"Loker Hydrocarbon Research Institute and Department of Chemistry University of Southern California  837 Bloom Walk Los Angeles CA 90089-1661 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6350-8325","authenticated-orcid":false,"given":"G.
