In particular, dehydrogenative decarbonylation of alcohols possesses a long\u2010standing challenge, as it requires the controlled coupling of oxidative alcohol activation with reductive C\u2500C bond cleavage, two intrinsically competing processes that are difficult to balance within a single catalytic system. Considering these, we demonstrate that CO\n                    <jats:sub>2<\/jats:sub>\n                    can resolve this mismatch by functioning as a dynamic redox shuttle in a heterogeneous photocatalytic platform. Under visible\u2010light irradiation, the photocatalyst promotes sequential dehydrogenation of primary alcohols to aldehydes, followed by C\u2500C bond scission and selective formation of alkanes. Mechanistic studies, including isotope labeling, radical trapping, atmosphere\u2010dependent reactivity, and advanced quantum mechanical calculations reveal that CO\n                    <jats:sub>2<\/jats:sub>\n                    is not incorporated into the products but instead transiently interacts with reduced iron sites to facilitate catalyst turnover, suppress unproductive H\n                    <jats:sub>2<\/jats:sub>\n                    evolution, and direct hydrogen equivalents toward C\u2500H bond formation. This redox\u2010shuttling function enables the integration of oxidative and reductive steps within a single photocatalytic cycle, thus opening new opportunities for steering complex redox transformations in photocatalysis.\n                  <\/jats:p>","DOI":"10.1002\/anie.9277722","type":"journal-article","created":{"date-parts":[[2026,7,24]],"date-time":"2026-07-24T10:23:17Z","timestamp":1784888597000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["CO\n                    <sub>2<\/sub>\n                    as a Redox Shuttle Enables Photocatalytic Dehydrogenative Decarbonylation of Biomass\u2010Derived Alcohols to Light Alkanes"],"prefix":"10.1002","volume":"65","author":[{"given":"Jun","family":"Hu","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Bayreuth  Bayreuth Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenhao","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Bayreuth  Bayreuth Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaoqin","family":"Zeng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Low Carbon Catalysis and Carbon Dioxide Utilization Lanzhou Institute of Chemical Physics Chinese Academy of Sciences  Lanzhou Gansu China"},{"name":"University of Chinese Academy of Science  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0130-8029","authenticated-orcid":false,"given":"Bruno Vinicius Manzolli","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Department of Inorganic Chemistry University of Wuppertal  Wuppertal Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nils","family":"Rockstroh","sequence":"additional","affiliation":[{"name":"Leibniz\u2010Institut f\u00fcr Katalyse e.V.
