The \u2022OH formation rate was compared using coumarin, and higher efficiency was proved for TiO2 than ZnO, while for 1,4-benzoquinone in O2-free suspensions, the higher contribution of the photogenerated electrons to the conversion was observed for ZnO than TiO2, especially at 398 nm irradiation. An extremely fast transformation and high quantum yield of SMP in the TiO2\/LED398nm process were observed. The transformation was fast in both O2 containing and O2-free suspensions and takes place via desulfonation, while in other cases, mainly hydroxylated products form. The effect of reaction parameters (methanol, dissolved O2 content, HCO3\u2212 and Cl\u2212) confirmed that a quite rarely observed energy transfer between the excited state P25 and SMP might be responsible for this unique behavior. In our opinion, these results highlight that \u201cnon-conventional\u201d mechanisms could occur even in the case of the well-known TiO2 photocatalyst, and the effect of wavelength is also worth investigating.<\/jats:p>","DOI":"10.3390\/ma15010049","type":"journal-article","created":{"date-parts":[[2021,12,23]],"date-time":"2021-12-23T02:01:19Z","timestamp":1640224879000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Wavelength Dependence of the Transformation Mechanism of Sulfonamides Using Different LED Light Sources and TiO2 and ZnO Photocatalysts"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8055-0974","authenticated-orcid":false,"given":"M\u00e1t\u00e9","family":"N\u00e1fr\u00e1di","sequence":"first","affiliation":[{"name":"Department of Inorganic and Analytical Chemistry, University of Szeged, D\u00f3m t\u00e9r 7, H-6720 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9869-9280","authenticated-orcid":false,"given":"T\u00fcnde","family":"Alapi","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Analytical Chemistry, University of Szeged, D\u00f3m t\u00e9r 7, H-6720 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luca","family":"Farkas","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Analytical Chemistry, University of Szeged, D\u00f3m t\u00e9r 7, H-6720 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6905-0546","authenticated-orcid":false,"given":"G\u00e1bor","family":"Bencsik","sequence":"additional","affiliation":[{"name":"Department of Physical Chemistry and Materials Science, University of Szeged, Rerrich B\u00e9la t\u00e9r 1, H-6720 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2033-0720","authenticated-orcid":false,"given":"G\u00e1bor","family":"Kozma","sequence":"additional","affiliation":[{"name":"Department of Applied and Environmental Chemistry, University of Szeged, Rerrich B\u00e9la t\u00e9r 1, H-6720 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9419-689X","authenticated-orcid":false,"given":"Kl\u00e1ra","family":"Hern\u00e1di","sequence":"additional","affiliation":[{"name":"Institute of Physical Metallurgy, Metal Forming and Nanotechnology, University of Miskolc, C\/2-5 Building 209, H-3515 Miskolc-Egyetemvaros, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"318","DOI":"10.1016\/S1473-3099(17)30753-3","article-title":"Discovery, Research, and Development of New Antibiotics: The WHO Priority List of Antibiotic-Resistant Bacteria and Tuberculosis","volume":"18","author":"Tacconelli","year":"2018","journal-title":"Lancet Infect.
