Although the one-pot sol-gel method leads to high-quality photocatalysts, areas remain for improvement. This study examines the impact of ethanol as a cosolvent in STO synthesis, focusing on optimizing the water-to-ethanol volume ratio. The findings reveal that a 1:3 ratio significantly enhances macropore formation and photocatalytic efficiency, achieving 42% NOx degradation under LED within three hours. Furthermore, incorporating 8.0 wt.% Ag into STO substantially improves visible light absorption and enables complete NOx elimination, thanks to enhanced charge separation and localized surface plasmon resonance. Even at high temperatures (1100 \u00b0C), the Ag-STO photocatalyst maintains partial activity, despite exceeding silver\u2019s melting point. These results highlight the potential of STO-based materials for industrial applications, positioning them as a promising solution for effective NOx mitigation.<\/jats:p>","DOI":"10.3390\/nano14201663","type":"journal-article","created":{"date-parts":[[2024,10,16]],"date-time":"2024-10-16T07:58:32Z","timestamp":1729065512000},"page":"1663","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Investigating the Synergistic Effect of Decoration and Doping in Silver\/Strontium Titanate for Air Remediation"],"prefix":"10.3390","volume":"14","author":[{"given":"Marcela","family":"Fr\u00edas Ord\u00f3\u00f1ez","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of Milan, Via Golgi 19, 20133 Milano, Italy"},{"name":"Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali (INSTM), Via Giusti 9, 50121 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisabetta","family":"Sacco","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Milan, Via Golgi 19, 20133 Milano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9242-6601","authenticated-orcid":false,"given":"Marco","family":"Scavini","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Milan, Via Golgi 19, 20133 Milano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8536-1398","authenticated-orcid":false,"given":"Giuseppina","family":"Cerrato","sequence":"additional","affiliation":[{"name":"Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali (INSTM), Via Giusti 9, 50121 Florence, Italy"},{"name":"Department of Chemistry, University of Turin, Via Giuria 7, 10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7566-6793","authenticated-orcid":false,"given":"Alessia","family":"Giordana","sequence":"additional","affiliation":[{"name":"Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali (INSTM), Via Giusti 9, 50121 Florence, Italy"},{"name":"Department of Chemistry, University of Turin, Via Giuria 7, 10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3127-8967","authenticated-orcid":false,"given":"Ermelinda","family":"Falletta","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Milan, Via Golgi 19, 20133 Milano, Italy"},{"name":"Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali (INSTM), Via Giusti 9, 50121 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9702-6949","authenticated-orcid":false,"given":"Claudia Letizia","family":"Bianchi","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Milan, Via Golgi 19, 20133 Milano, Italy"},{"name":"Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali (INSTM), Via Giusti 9, 50121 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"19615","DOI":"10.1007\/s11356-021-13208-x","article-title":"Air pollution exposure\u2014The (in)visible risk factor for respiratory diseases","volume":"28","author":"Tudorache","year":"2021","journal-title":"Environ.
