The photocatalytic tests were performed in alkaline aqueous solutions (pH = 10) of three differently substituted phenols (phenol (I), 4,4\u2032-isopropylidenebisphenol (II), and 4,4\u2032-isopropylidenebis(2,6-dibromophenol) (III)). The activity of the catalysts was evaluated by monitoring I, II, III degradation in the reaction mixture. The physicochemical properties (particle size, \u03b6-potential, Ebg, Eu, E0cb, E0vb, \u03c3o, KL) of the catalysts were established, and we demonstrated their influence on degradation reaction kinetics. Substrate degradation rates are consistent with first-order kinetics. The apparent conversion constants of the tested compounds (kapp) in all cases reveal the sulfur-loaded catalyst S2 to show the best photocatalytic activity (for compound I and II S1 and S2 are similarly effective). The different efficiency of photocatalytic degradation I, II and III can be explained by the interactions between the catalyst and the substrate solution. The presence of bromine substituents in the benzene ring additionally allows reduction reactions. The yield of bromide ion release in the degradation reaction III corresponds to the Langmuir constant. The mixed oxidation-reduction degradation mechanism results in higher degradation efficiency. In general, the presence of sulfur atoms in the catalyst network improves the degradation efficiency, but too much sulfur is not desired for the reduction pathway.<\/jats:p>","DOI":"10.3390\/ma15010361","type":"journal-article","created":{"date-parts":[[2022,1,7]],"date-time":"2022-01-07T01:14:02Z","timestamp":1641518042000},"page":"361","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Photocatalytic Degradation of 4,4\u2032-Isopropylidenebis(2,6-dibromophenol) on Sulfur-Doped Nano TiO2"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0014-0866","authenticated-orcid":false,"given":"Joanna B.","family":"Kisa\u0142a","sequence":"first","affiliation":[{"name":"College of Natural Sciences, University of Rzeszow, Pigonia 1 Str., 35-310 Rzeszow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3883-2879","authenticated-orcid":false,"given":"Gerald","family":"H\u00f6rner","sequence":"additional","affiliation":[{"name":"Inorganic Chemistry IV, University of Bayreuth, Universit\u00e4tsstrasse 30, D-95440 Bayreuth, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriana","family":"Barylyak","sequence":"additional","affiliation":[{"name":"Department of Therapeutic Dentistry, Danylo Halitsky Lviv National Medicinal University, Pekarska Str. 69, 79010 Lviv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4953-6960","authenticated-orcid":false,"given":"Dariusz","family":"Pogocki","sequence":"additional","affiliation":[{"name":"College of Natural Sciences, University of Rzeszow, Pigonia 1 Str., 35-310 Rzeszow, Poland"},{"name":"Institute of Nuclear Chemistry and Technology, Dorodna 16, 03-195 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7957-0502","authenticated-orcid":false,"given":"Yaroslav","family":"Bobitski","sequence":"additional","affiliation":[{"name":"College of Natural Sciences, University of Rzeszow, Pigonia 1 Str., 35-310 Rzeszow, Poland"},{"name":"Department of Photonics, Lviv Polytechnic National University, S.
