The synergistic integration of rGO and TiO2, through the formation of Ti\u2013O\u2013C bonds, offers an interesting opportunity to design photocatalyst nanocomposite materials with the maximum absorption shift to the visible region of the spectra, where photodegradation can be activated not only with UV but also with the visible part of natural solar irradiation. TiO2@rGO nanocomposites with different content of rGO have been self-assembled by the hydrothermal method followed by calcination treatment. The morphological and structural analysis of the synthesized photocatalysts was performed by FTIR, XRD, XPS, UV-Vis DRS, SEM\/EDX, and Raman spectroscopy. The effectiveness of the synthesized nanocomposites as photocatalysts was examined through the photodegradation of methylene blue (MB) and rhodamine B (RhB) dye under artificial solar-like radiation. The influence of rGO concentration (5 and 15 wt.%) on TiO2 performance for photodegradation of the different dyes was monitored by UV-Vis spectroscopy. The obtained results showed that the synthesized TiO2@rGO nanocomposites significantly increased the decomposition of RhB and MB compared to the synthesized TiO2 photocatalyst. Furthermore, TiO2@rGO nanocomposite with high contents of rGO (15 wt.%) presented an improved performance in photodegradation of MB (98.1%) and RhB (99.8%) after 120 min of exposition to solar-like radiation. These results could be mainly attributed to the decrease of the bandgap of synthesized TiO2@rGO nanocomposites with the increased contents of rGO. Energy gap (Eg) values of nanocomposites are 2.71 eV and 3.03 eV, when pure TiO2 particles have 3.15 eV. These results show the potential of graphene-based TiO2 nanocomposite to be explored as a highly efficient solar light-driven photocatalyst for water purification.<\/jats:p>","DOI":"10.3390\/app11093966","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T21:18:20Z","timestamp":1619558300000},"page":"3966","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":72,"title":["Graphene-Based TiO2 Nanocomposite for Photocatalytic Degradation of Dyes in Aqueous Solution under Solar-Like Radiation"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3558-8687","authenticated-orcid":false,"given":"Martina","family":"Kocijan","sequence":"first","affiliation":[{"name":"Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb, Ivana Lu\u010di\u0107a 5, 10000 Zagreb, Croatia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3212-277X","authenticated-orcid":false,"given":"Lidija","family":"\u0106urkovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb, Ivana Lu\u010di\u0107a 5, 10000 Zagreb, Croatia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1529-8009","authenticated-orcid":false,"given":"Davor","family":"Ljubas","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb, Ivana Lu\u010di\u0107a 5, 10000 Zagreb, Croatia"}]},{"given":"Katarina","family":"Mu\u017eina","sequence":"additional","affiliation":[{"name":"Faculty of Chemical Engineering and Technology, University of Zagreb, Trg Marka Maruli\u0107a 20, 10000 Zagreb, Croatia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0997-3960","authenticated-orcid":false,"given":"Ivana","family":"Ba\u010di\u0107","sequence":"additional","affiliation":[{"name":"Forensic Science Centre \u201cIvan Vu\u010deti\u0107\u201d, Ministry of the Interior, Ilica 335, 10000 Zagreb, Croatia"}]},{"given":"Tina","family":"Rado\u0161evi\u0107","sequence":"additional","affiliation":[{"name":"Jo\u017eef Stefan Institute, Jamova Cesta 39, SI-1000 Ljubljana, Slovenia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7892-8608","authenticated-orcid":false,"given":"Matejka","family":"Podlogar","sequence":"additional","affiliation":[{"name":"Jo\u017eef Stefan Institute, Jamova Cesta 39, SI-1000 Ljubljana, Slovenia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6318-1425","authenticated-orcid":false,"given":"Igor","family":"Bdikin","sequence":"additional","affiliation":[{"name":"Centre for Mechanical Technology and Automation (TEMA), Mechanical Engineering Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3214-8002","authenticated-orcid":false,"given":"Gonzalo","family":"Otero-Irurueta","sequence":"additional","affiliation":[{"name":"Centre for Mechanical Technology and Automation (TEMA), Mechanical Engineering Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3555-8218","authenticated-orcid":false,"given":"Mar\u00eda J.","family":"Hortig\u00fcela","sequence":"additional","affiliation":[{"name":"Centre for Mechanical Technology and Automation (TEMA), Mechanical Engineering Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Gil","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Centre for Mechanical Technology and Automation (TEMA), Mechanical Engineering Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"110906","DOI":"10.1016\/j.jenvman.2020.110906","article-title":"Present applications of titanium dioxide for the photocatalytic removal of pollutants from water: A review","volume":"270","author":"Gopinath","year":"2020","journal-title":"J.
