In this study, we unveil the crucial role of PdAu\/CeO\n                    <jats:sub>2<\/jats:sub>\n                    catalysts in enabling selective methane transformation under mild conditions, using only water as the sole oxidant. Through a combination of experimental techniques, including XPS and catalytic testing, alongside density functional theory (DFT) calculations, we demonstrate that a Pd\n                    <jats:sub>0.3<\/jats:sub>\n                    Au\n                    <jats:sub>0.7<\/jats:sub>\n                    \/CeO\n                    <jats:sub>2<\/jats:sub>\n                    catalyst, which predominantly exposes isolated Pd atoms, achieves remarkable methanol selectivity (\u223c80%) at 500\u00a0K with a 1:1 methane\u2010to\u2010water ratio. While Pd\/CeO\n                    <jats:sub>2<\/jats:sub>\n                    efficiently activates methane, its tendency for overreaction leads to complete methanol decomposition, thereby limiting selectivity. Alloying Pd with Au on ceria mitigates this over\u2010reactivity, preventing methanol degradation while maintaining sufficient catalytic activity. The PdAu\/CeO\n                    <jats:sub>2<\/jats:sub>\n                    composite exhibits a synergistic effect: Pd in contact with the ceria support facilitates methane activation and water dissociation, while Au fine\u2010tunes reactivity to promote methanol formation. DFT calculations confirm that isolated Pd sites at the PdAu\/CeO\n                    <jats:sub>2<\/jats:sub>\n                    interface play a key role in balancing activity and selectivity. This work underscores the importance of alloy\/oxide interfaces in controlling selective methane conversion with water and offers valuable insights for designing highly efficient catalysts for methanol synthesis.\n                  <\/jats:p>","DOI":"10.1002\/anie.202505716","type":"journal-article","created":{"date-parts":[[2025,7,25]],"date-time":"2025-07-25T06:54:22Z","timestamp":1753426462000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Engineering PdAu\/CeO\n                    <sub>2<\/sub>\n                    Alloy\/Oxide Interfaces for Selective Methane\u2010to\u2010Methanol Conversion with Water"],"prefix":"10.1002","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9419-0786","authenticated-orcid":false,"given":"Estefan\u00eda","family":"Fern\u00e1ndez\u2010Villanueva","sequence":"first","affiliation":[{"name":"Universitat Polit\u00e8cnica de Val\u00e8ncia  Cam\u00ed de Vera s\/n Valencia 46022 Spain"},{"name":"Instituto de Cat\u00e1lisis y Petroleoqu\u00edmica (ICP\u2010CSIC)  C\/ de Marie Curie 2 Madrid 28049 Spain"},{"name":"Departamento de F\u0131\u0301sica Te\u00f3rica de la Materia Condensada Universidad Aut\u00f3noma de Madrid Ciudad Universitaria de Cantoblanco  Madrid E\u201028049 Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6236-5545","authenticated-orcid":false,"given":"Pedro J.","family":"Ram\u00edrez","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias Universidad Central de Venezuela Caracas Distrito Capital 1020\u2010A Venezuela"},{"name":"Zoneca\u2010CENEX R&amp;D Laboratories  Alta Vista Monterrey 64770 Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4058-4023","authenticated-orcid":false,"given":"Pablo G.","family":"Lustemberg","sequence":"additional","affiliation":[{"name":"Instituto de Cat\u00e1lisis y Petroleoqu\u00edmica (ICP\u2010CSIC)  C\/ de Marie Curie 2 Madrid 28049 Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5896-541X","authenticated-orcid":false,"given":"Rub\u00e9n","family":"P\u00e9rez","sequence":"additional","affiliation":[{"name":"Departamento de F\u0131\u0301sica Te\u00f3rica de la Materia Condensada Universidad Aut\u00f3noma de Madrid Ciudad Universitaria de Cantoblanco  Madrid E\u201028049 Spain"},{"name":"Condensed Matter Physics Center (IFIMAC) Universidad Aut\u00f3noma de Madrid Ciudad Universitaria de Cantoblanco  Madrid E\u201028049 Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2408-8898","authenticated-orcid":false,"given":"M.
