To upcycle waste plastics into value-added chemicals is a global challenge. Despite significant progress in pyrolysis and hydrocracking, which mainly leads to the formation of pyrolysis oil, catalytic upcycling to value-added aromatics, including benzene, toluene and xylene (BTX), in one step, is still limited by high reaction temperatures (&amp;gt;500\u00b0C) and a low yield. We report herein CO2-facilitated upcycling of polyolefins and their plastic products to aromatics below 300\u00b0C, enabled by a bifunctional Pt\/MnOx-ZSM-5 catalyst. ZSM-5 catalyzes cracking of polyolefins and aromatization, generating hydrogen at the same time, while Pt\/MnOx catalyzes the reaction of hydrogen with CO2, consequently driving the reaction towards aromatization. Isotope experiments reveal that 0.2\u00a0kg CO2 is consumed per 1.0\u00a0kg polyethylene and 90% of the consumed CO2 is incorporated into the aromatic products. Furthermore, this new process yields 0.63\u00a0kg aromatics (BTX accounting for 60%), comparing favorably with the conventional pyrolysis or hydrocracking processes, which produce only 0.33\u00a0kg aromatics. In this way, both plastic waste and the greenhouse gas CO2 are turned into carbon resources, providing a new strategy for combined waste plastics upcycling and carbon dioxide utilization.<\/jats:p>","DOI":"10.1093\/nsr\/nwae097","type":"journal-article","created":{"date-parts":[[2024,3,15]],"date-time":"2024-03-15T21:20:01Z","timestamp":1710537601000},"source":"Crossref","is-referenced-by-count":58,"title":["CO2-facilitated upcycling of polyolefin plastics to aromatics at low temperature"],"prefix":"10.1093","volume":"11","author":[{"given":"Yi","family":"Ding","sequence":"first","affiliation":[{"name":"State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences , Dalian 116023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuchi","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences , Dalian 116023 , China"},{"name":"University of Chinese Academy of Sciences , Beijing 100049 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences , Dalian 116023 , China"},{"name":"University of Chinese Academy of Sciences , Beijing 100049 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Shao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences , Dalian 116023 , China"},{"name":"Department of Chemical Physics, University of Science and Technology of China , Hefei 230026 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiulian","family":"Pan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences , Dalian 116023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinhe","family":"Bao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences , Dalian 116023 , China"},{"name":"Department of Chemical Physics, University of Science and Technology of China , Hefei 230026 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,3,15]]},"reference":[{"key":"2024042415270652400_bib1","doi-asserted-by":"publisher","first-page":"15402","DOI":"10.1002\/anie.201915651","article-title":"Beyond mechanical recycling: giving new life to plastic waste","volume":"59","author":"Vollmer","year":"2020","journal-title":"Angew Chem Int Ed"},{"key":"2024042415270652400_bib2","doi-asserted-by":"publisher","first-page":"272","DOI":"10.1038\/s41586-022-05422-5","article-title":"Plastic futures and their CO2 emissions","volume":"612","author":"Stegmann","year":"2022","journal-title":"Nature"},{"key":"2024042415270652400_bib3","volume-title":"Global Plastics Outlook","author":"OECD","year":"2022"},{"key":"2024042415270652400_bib4","doi-asserted-by":"publisher","first-page":"e1700782","DOI":"10.1126\/sciadv.1700782","article-title":"Production, use, and fate of all plastics ever made","volume":"3","author":"Geyer","year":"2017","journal-title":"Sci Adv"},{"key":"2024042415270652400_bib5","doi-asserted-by":"publisher","first-page":"2318","DOI":"10.1016\/j.chempr.2023.05.017","article-title":"Bifunctional tandem catalytic upcycling of polyethylene to surfactant-range alkylaromatics","volume":"9","author":"Sun","year":"2023","journal-title":"Chem"},{"key":"2024042415270652400_bib6","doi-asserted-by":"publisher","first-page":"4513","DOI":"10.1021\/acs.est.3c00263","article-title":"What to do about plastics?
