Herein, we report an N,O-dual-coordinated iron single-atom catalyst (Fe\u2013N2O2-hCN) integrated with palladium nanoparticles (Pd NPs) for efficient hydrothermal Fenton-like upcycling of PVC into fuel-range hydrocarbons. The asymmetric Fe\u2013N2O2 configuration modulates the electronic structure of Fe centers, promoting H2O2 activation and hydroxyl radical generation for efficient C\u2013Cl and C\u2013C bond cleavage under mild conditions, outperforming the conventional Fe\u2013N4 catalyst. The bifunctional Pd NPs\/Fe\u2013N2O2-hCN system achieves high PVC degradation efficiency (97.38%) and near-complete dechlorination, while selectively hydrogenating depolymerized intermediates into fuel-range alkanes (C3\u2013C20) with a high selectivity (86.01%). Mechanistic studies reveal enhanced electron transfer and a lowered energy barrier for H2O2 dissociation, with Pd NPs generating reactive hydrogen species for olefin saturation. Life cycle assessment (LCA) demonstrates a 77% reduction in carbon emissions and significantly lower eco-costs than incineration. This work provides a coordination-engineered platform for converting hazardous plastic waste into valuable fuels, advancing a circular plastic economy.<\/jats:p>","DOI":"10.1021\/acs.est.6c07414","type":"journal-article","created":{"date-parts":[[2026,7,2]],"date-time":"2026-07-02T16:57:18Z","timestamp":1783011438000},"page":"24507-24519","source":"Crossref","is-referenced-by-count":2,"title":["Coordination-Engineered\nFe Single Atoms Enable Synergistic\nPVC Upcycling into Fuel-Range Hydrocarbons via Fenton-Like Pathway"],"prefix":"10.1021","volume":"60","author":[{"given":"Qingyun","family":"Bai","sequence":"first","affiliation":[{"name":"Donghua University , , ,","place":["Shanghai, China, 201620"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiuyi","family":"Wang","sequence":"additional","affiliation":[{"name":"Dalian Institute of Chemical Physics, Chinese Academy of Sciences , , ,","place":["Dalian, China, 116023"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7245-179X","authenticated-orcid":true,"given":"Xing","family":"Xu","sequence":"additional","affiliation":[{"name":"Shandong University , , ,","place":["Qingdao, China, 266237"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7353-842X","authenticated-orcid":true,"given":"Xuning","family":"Li","sequence":"additional","affiliation":[{"name":"Dalian Institute of Chemical Physics, Chinese Academy of Sciences , , ,","place":["Dalian, China, 116023"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3085-0789","authenticated-orcid":true,"given":"Xie","family":"Quan","sequence":"additional","affiliation":[{"name":"Dalian University of Technology , , ,","place":["Dalian, China, 116024"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8404-3806","authenticated-orcid":true,"given":"Yanbiao","family":"Liu","sequence":"additional","affiliation":[{"name":"Donghua University , , ,","place":["Shanghai, China, 201620"]},{"name":"Dalian University of Technology , , ,","place":["Dalian, China, 116024"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,2]]},"reference":[{"issue":"3","key":"2026090307130276600_cit1","doi-asserted-by":"publisher","first-page":"2822","DOI":"10.1021\/jacs.4c16145","article-title":"Upcycling poly(vinyl chloride) and\npolystyrene plastics using photothermal conversion","volume":"147","author":"Jiang","year":"2025","journal-title":"J.
