Here, we show that engineering the dielectric environment in Au\/CeO2 using ultrathin nanoporous Ceria transforms plasmonically activated volume (PAV) on CeO2 side from interface-confined plasmonic excitation into a spatially extended, volume-activated process. meV-resolution electron energy-loss spectroscopy visualizes LSPR propagation throughout the porous framework, while photoluminescence spectroscopy reveals an enhanced contribution from fast charge-transfer channels. Quantitative analysis establishes the correlation among the PAV, fast charge transfer, and carrier utilization efficiency. These findings highlight the importance of semiconductor-side carrier dynamics in plasmonic heterostructures and establish dielectric-environment engineering as an effective strategy for extending plasmonic functionality beyond the immediate metal\u2013semiconductor interface.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6c02017","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T15:30:12Z","timestamp":1784734212000},"page":"8969-8976","source":"Crossref","is-referenced-by-count":0,"title":["Expanding the\nPlasmonically Activated Volume for Enhanced\nFast Carrier Extraction in Au\/CeO2 Photocatalysts"],"prefix":"10.1021","volume":"17","author":[{"given":"Ying","family":"Zhao","sequence":"first","affiliation":[{"name":"Shaanxi Normal University , , ,","place":["Xi\u2019an, China, 710119"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Liu","sequence":"additional","affiliation":[{"name":"Shaanxi Normal University , , ,","place":["Xi\u2019an, China, 710119"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fei","family":"Rao","sequence":"additional","affiliation":[{"name":"Shaanxi Normal University , , ,","place":["Xi\u2019an, China, 710119"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5708-9446","authenticated-orcid":true,"given":"Gangqiang","family":"Zhu","sequence":"additional","affiliation":[{"name":"Shaanxi Normal University , , ,","place":["Xi\u2019an, China, 710119"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6838-5678","authenticated-orcid":true,"given":"Lujun","family":"Zhu","sequence":"additional","affiliation":[{"name":"Shaanxi Normal University , , ,","place":["Xi\u2019an, China, 710119"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,22]]},"reference":[{"key":"2026080609092108400_cit1","doi-asserted-by":"publisher","first-page":"889","DOI":"10.1126\/science.abn5636","article-title":"Earth-abundant photocatalyst for H2 generation from NH3 with light-emitting diode illumination","volume":"378","author":"Yuan","year":"2022","journal-title":"Science"},{"key":"2026080609092108400_cit2","doi-asserted-by":"publisher","first-page":"95","DOI":"10.1038\/nphoton.2013.238","article-title":"Plasmon-induced\nHot-electron Generation at Nanoparticle\/metal-Oxide Interfaces For\nPhotovoltaic and Photocatalytic Devices","volume":"8","author":"Clavero","year":"2014","journal-title":"Nat.\nPhotonics"},{"key":"2026080609092108400_cit3","doi-asserted-by":"publisher","first-page":"11017","DOI":"10.1039\/D5CS00417A","article-title":"Photothermal Methane Dry Reforming:\nCatalyst Architectures, Mechanistic Pathways, And Future Challenges","volume":"54","author":"Yang","year":"2025","journal-title":"Chem.
