The aqueous environment is highly exposed to the harmful effects of these organic compounds. Furthermore, the commonly applied conventional purification techniques are not sufficient enough. Heterogeneous photocatalysis and the photo-Fenton process are effective, low-cost and green alternatives for the removal of organic pollutants. In this study, different iron(III) oxide\/titanium(IV) oxide\/polyvinyl chloride (Fe2O3\/TiO2\/PVC) nanocomposites in tablet form were investigated in the photodegradation of methylene blue (MB) under simulated sunlight, and their possible antibacterial effects were examined. The newly synthesized nanocomposites were characterized by scanning electron microscope, X-ray diffraction, UV\u2013Vis diffuse reflectance spectroscopy, and Raman spectroscopy. The results showed a hematite crystal form in the case of Fe2O3(2) and Fe2O3 samples, while the Fe2O3(1) sample showed a combination of hematite and synthetic mineral akaganeite. The highest photocatalytic efficiency was achieved in the presence of Fe2O3\/TiO2\/PVC, when 70.6% of MB was removed. In addition, the possible photo-cleaning and reuse of the mentioned photocatalyst was also examined. Based on the results, it can be seen that the activity did not decrease after five successive runs. Nanocomposites also exhibited mild antibacterial effects against the two tested Gram-positive bacteria (S. aureus and B. cereus).<\/jats:p>","DOI":"10.3390\/nano13030460","type":"journal-article","created":{"date-parts":[[2023,1,23]],"date-time":"2023-01-23T05:46:11Z","timestamp":1674452771000},"page":"460","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Reusable Fe2O3\/TiO2\/PVC Photocatalysts for the Removal of Methylene Blue in the Presence of Simulated Solar Radiation"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7604-2747","authenticated-orcid":false,"given":"Ivana","family":"Jagodi\u0107","sequence":"first","affiliation":[{"name":"Department of Chemistry, Biochemistry and Environmental Protection,  Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 3, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Imre","family":"Guth","sequence":"additional","affiliation":[{"name":"Department of Physics, Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 4, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana","family":"Luki\u0107-Petrovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Physics, Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 4, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8179-8285","authenticated-orcid":false,"given":"Dragana","family":"Tamind\u017eija","sequence":"additional","affiliation":[{"name":"Department of Biology and Ecology, Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 2, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4504-291X","authenticated-orcid":false,"given":"Daniela","family":"\u0160oji\u0107 Merkulov","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Biochemistry and Environmental Protection,  Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 3, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6419-7576","authenticated-orcid":false,"given":"Nina","family":"Fin\u010dur","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Biochemistry and Environmental Protection,  Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 3, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3600-0075","authenticated-orcid":false,"given":"Szabolcs","family":"Bogn\u00e1r","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Biochemistry and Environmental Protection,  Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 3, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0342-6114","authenticated-orcid":false,"given":"Predrag","family":"Putnik","sequence":"additional","affiliation":[{"name":"Department of Food Technology, University North, Trg dr. \u017darka Dolinara 1, 48000 Koprivnica, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nemanja","family":"Bani\u0107","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Biochemistry and Environmental Protection,  Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovi\u0107a 3, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"75","DOI":"10.1016\/j.jhazmat.2005.03.008","article-title":"Decolourization of aqueous dye solutions by a novel adsorbent: Application of statistical designs and surface plots for the optimization and regression analysis","volume":"122","author":"Ravikumar","year":"2005","journal-title":"J.
