A series of heterojunction photocatalysts with different compositions was prepared and evaluated, identifying the material containing 10%\n                    <jats:sub>W\/W<\/jats:sub>\n                    CsPbCl\n                    <jats:sub>3<\/jats:sub>\n                    as the most efficient catalyst. Under mild conditions and using molecular oxygen as the sole oxidant, a broad range of primary and secondary benzylic alcohols was selectively converted into the corresponding aldehydes and ketones in good to excellent yields. The methodology proved scalable to gram\u2010scale synthesis and the photocatalyst could be readily recovered and reused over multiple cycles while preserving both catalytic activity and structural integrity. Mechanistic studies indicate that substrate activation proceeds through distinct pathways depending on its redox properties, involving either direct single\u2010electron oxidation or oxidation mediated by superoxide radical anion. This work demonstrates the potential of metal halide perovskite\/carbon nitride heterojunctions as robust and recyclable photocatalysts for sustainable aerobic oxidation processes and green organic synthesis.\n                  <\/jats:p>","DOI":"10.1002\/cssc.71146","type":"journal-article","created":{"date-parts":[[2026,10,14]],"date-time":"2026-10-14T16:55:53Z","timestamp":1791996953000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Engineering\n                    <i>g<\/i>\n                    \u2010C\n                    <sub>3<\/sub>\n                    N\n                    <sub>4<\/sub>\n                    \/CsPbCl\n                    <sub>3<\/sub>\n                    Heterojunctions for Selective Photocatalytic Oxidation of Benzylic Alcohols"],"prefix":"10.1002","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-8994-4728","authenticated-orcid":false,"given":"Camilla","family":"Callegari","sequence":"first","affiliation":[{"name":"PhotoGreen Lab Department of Chemistry University of Pavia  Pavia Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0759-4589","authenticated-orcid":false,"given":"Emanuele","family":"Bosetti","sequence":"additional","affiliation":[{"name":"PhotoGreen Lab Department of Chemistry University of Pavia  Pavia Italy"},{"name":"Energy and Materials Chemistry Group Department of Chemistry and INSTM University of Pavia  Pavia Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giulia","family":"Giovilli","sequence":"additional","affiliation":[{"name":"Energy and Materials Chemistry Group Department of Chemistry and INSTM University of Pavia  Pavia Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2201-4828","authenticated-orcid":false,"given":"Davide","family":"Ravelli","sequence":"additional","affiliation":[{"name":"PhotoGreen Lab Department of Chemistry University of Pavia  Pavia Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4724-2376","authenticated-orcid":false,"given":"Lorenzo","family":"Malavasi","sequence":"additional","affiliation":[{"name":"Energy and Materials Chemistry Group Department of Chemistry and INSTM University of Pavia  Pavia Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,14]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"crossref","first-page":"7245","DOI":"10.1039\/D2CY01322C","article-title":"Advances and Future Trends in Selective Oxidation Catalysis: A Critical Review","volume":"12","author":"Yadav G.
