Thermal pre-treatment of commercial TiO2 Degussa P25 (DTiO2) and Hombifine N (HTiO2) in the range from 600 to 800 \u00b0C was carried out followed by the deposition of copper oxides (1\u201310 wt. % of Cu). The morphology and chemical state of synthesized photocatalysts were studied using X-ray diffraction, UV\u2013Vis diffuse reflectance spectroscopy, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, and XANES\/EXAFS X-ray absorption spectroscopy. Photocatalytic activity was tested in the hydrogen evolution from aqueous solutions of glycerol under ultraviolet (\u03bb = 381 nm) and visible (\u03bb = 427 nm) light. The photocatalysts 2% CuOx\/DTiO2 T750 and 5% CuOx\/DTiO2 T700 showed the highest activity under UV irradiation (\u03bb = 380 nm), with the rate of H2 evolution at the level of 2.5 mmol (H2) g\u22121 h\u22121. Under the visible light irradiation (\u03bb = 427 nm), the highest activity of 0.6 mmol (H2) g\u22121 h\u22121 was achieved with the 5% CuOx\/DTiO2 T700 photocatalyst. The activity of these photocatalysts is 50% higher than that of the platinized 1% Pt\/DTiO2 sample. Thus, it was shown for the first time that a simple heat treatment of a commercial titanium dioxide in combination with a deposition of non-noble metal particles led to a significant increase in the activity of photocatalysts and made it possible to obtain materials that were active in hydrogen production under visible light irradiation.<\/jats:p>","DOI":"10.3390\/nano12183106","type":"journal-article","created":{"date-parts":[[2022,9,8]],"date-time":"2022-09-08T01:40:13Z","timestamp":1662601213000},"page":"3106","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Copper-Modified Titania-Based Photocatalysts for the Efficient Hydrogen Production under UV and Visible Light from Aqueous Solutions of Glycerol"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4150-7049","authenticated-orcid":false,"given":"Anna Yu.","family":"Kurenkova","sequence":"first","affiliation":[{"name":"Federal Research Center, Boreskov Institute of Catalysis SB RAS, Lavrentieva Ave. 5, 630090 Novosibirsk, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anastasiya Yu.","family":"Yakovleva","sequence":"additional","affiliation":[{"name":"Federal Research Center, Boreskov Institute of Catalysis SB RAS, Lavrentieva Ave. 5, 630090 Novosibirsk, Russia"},{"name":"Department of Natural Science, Novosibirsk State University, Pirogova St. 1, 630090 Novosibirsk, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9610-9921","authenticated-orcid":false,"given":"Andrey A.","family":"Saraev","sequence":"additional","affiliation":[{"name":"Federal Research Center, Boreskov Institute of Catalysis SB RAS, Lavrentieva Ave. 5, 630090 Novosibirsk, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3230-3335","authenticated-orcid":false,"given":"Evgeny Yu.","family":"Gerasimov","sequence":"additional","affiliation":[{"name":"Federal Research Center, Boreskov Institute of Catalysis SB RAS, Lavrentieva Ave. 5, 630090 Novosibirsk, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8944-7666","authenticated-orcid":false,"given":"Ekaterina A.","family":"Kozlova","sequence":"additional","affiliation":[{"name":"Federal Research Center, Boreskov Institute of Catalysis SB RAS, Lavrentieva Ave. 5, 630090 Novosibirsk, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1516-2817","authenticated-orcid":false,"given":"Vasily V.","family":"Kaichev","sequence":"additional","affiliation":[{"name":"Federal Research Center, Boreskov Institute of Catalysis SB RAS, Lavrentieva Ave. 5, 630090 Novosibirsk, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"972","DOI":"10.1126\/science.1103197","article-title":"Sustainable hydrogen production","volume":"305","author":"Turner","year":"2004","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"28349","DOI":"10.1016\/j.ijhydene.2017.09.093","article-title":"Effect of surface properties of copper-modified commercial titanium dioxide photocatalysts on hydrogen production through photoreforming of alcohols","volume":"42","author":"Clarizia","year":"2017","journal-title":"Int.
