Initially, a one-step hydrothermal technique facilitated the direct growth of single-crystal Na2Ti3O7 nanowires onto a flexible Ti foil. Subsequently, a two-step wet chemical process facilitated the sequential deposition of an RF layer and Ag nanoparticles onto the Na2Ti3O7 nanowires at a low reaction temperature. Optimal concentrations of silver nitrate and L-ascorbic acid can lead to the cultivation of Na2Ti3O7@RF@Ag heterostructures exhibiting heightened surface-enhanced Raman scattering (SERS), which is particularly beneficial for the detection of rhodamine B (RhB) molecules. This phenomenon can be ascribed to the distinctive geometry of the Na2Ti3O7@RF@Ag heterostructures, which offer an increased number of hot spots and surface-active sites, thereby showcasing notable SERS enhancement, commendable reproducibility, and enduring stability over the long term. Furthermore, the Na2Ti3O7@RF@Ag heterostructures demonstrate remarkable follow-up as first-order chemical kinetic and recyclable photocatalysts for the photodecomposition of an RhB solution under UV light irradiation. This result can be attributed to the enhanced inhibition of electron\u2013hole pair recombination and increased surface-active sites.<\/jats:p>","DOI":"10.3390\/molecules29010218","type":"journal-article","created":{"date-parts":[[2023,12,31]],"date-time":"2023-12-31T06:00:21Z","timestamp":1704002421000},"page":"218","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Na2Ti3O7@RF@Ag Heterostructures as Efficient Substrates for SERS and Photocatalytic Applications"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5474-680X","authenticated-orcid":false,"given":"Yu-Cheng","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, Feng Chia University, Taichung 40724, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I-Chun","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Feng Chia University, Taichung 40724, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning-Chien","family":"Chin","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Feng Chia University, Taichung 40724, Taiwan"},{"name":"Department of Orthopedics, Antai Tian-Sheng Memorial Hospital, Antai Medical Care Corporation, Pingtung 92842, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sin-Ei","family":"Juang","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Feng Chia University, Taichung 40724, Taiwan"},{"name":"Department of Anesthesiology, Kaohsiung Chang Gung Memorial Hospital, Chang Gung University College of Medicine, Kaohsiung 83301, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4616-437X","authenticated-orcid":false,"given":"Chia-Man","family":"Chou","sequence":"additional","affiliation":[{"name":"Department of Surgery, Taichung Veterans General Hospital, Taichung 40705, Taiwan"},{"name":"College of Medicine, National Yang Ming Chiao Tung University, Taipei 11221, Taiwan"},{"name":"Department of Post-Baccalaureate Medicine, National Chung Hsing University, Taichung 40227, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11517","DOI":"10.1039\/D1TC02134F","article-title":"Towards practical and sustainable SERS: A review of recent developments in the construction of multifunctional enhancing substrates","volume":"9","author":"Li","year":"2021","journal-title":"J.
