In the present work, silica-supported FePO4 and Fe-Mo-O catalysts are prepared, their phase composition, and catalytic properties are studied in the process of selective oxidation of propylene glycol into valuable mono- and bicarbonyl compounds, namely, hydroxyacetone and methylglyoxal. A comparative analysis of the main routes of propylene glycol adsorption with its subsequent oxidative conversion into carbonyl products is carried out. The DFT calculations show that in the presence of adsorbed oxygen atom, the introduction of the phosphate moiety to the Fe-containing site strengthens the alcohol adsorption on the catalyst surface with the formation of the 1,2-propanedioxy (\u2013OCH(CH3)CH2O\u2013) intermediate at the active site. The introduction of the molybdenum moiety to the Fe-containing site in the presence of the adsorbed oxygen atom is also energetically favorable, however, the interaction energy is found by 100 kJ\/mol higher compared to the case with phosphate moiety that leads to an increase in the propylene glycol conversion while maintaining high selectivity towards C3 products. The catalytic properties of the synthesized iron-containing catalysts are experimentally compared with those of Ag\/SiO2 sample. The synthesized FePO4\/SiO2 and Fe-Mo-O\/SiO2 catalysts are not inferior to the silver-containing catalyst and provide ~70% selectivity towards C3 products, while the main part of propylene glycol is converted into methylglyoxal in contrast to the Ag\/SiO2 catalyst featuring the selective transformation of only the secondary C-OH group in the substrate molecule under the studied conditions with the formation of hydroxyacetone. Thus, supported Fe-Mo-O\/SiO2 catalysts are promising for the selective oxidation of polyatomic alcohols under low-temperature conditions.<\/jats:p>","DOI":"10.3390\/ma15051906","type":"journal-article","created":{"date-parts":[[2022,3,6]],"date-time":"2022-03-06T20:38:16Z","timestamp":1646599096000},"page":"1906","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Modifier Effect in Silica-Supported FePO4 and Fe-Mo-O Catalysts for Propylene Glycol Oxidation"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6333-441X","authenticated-orcid":false,"given":"Darya","family":"Savenko","sequence":"first","affiliation":[{"name":"Laboratory of Catalytic Research, Tomsk State University, 36 Lenin Avenue, 634050 Tomsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikhail","family":"Salaev","sequence":"additional","affiliation":[{"name":"Laboratory of Catalytic Research, Tomsk State University, 36 Lenin Avenue, 634050 Tomsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valerii","family":"Dutov","sequence":"additional","affiliation":[{"name":"Laboratory of Catalytic Research, Tomsk State University, 36 Lenin Avenue, 634050 Tomsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1365-9221","authenticated-orcid":false,"given":"Sergei","family":"Kulinich","sequence":"additional","affiliation":[{"name":"Research Institute of Science & Technology, Tokai University, Hiratsuka 259-1292, Kanagawa, Japan"},{"name":"School of Natural Sciences, Far Eastern Federal University, 690091 Vladivostok, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1221-8851","authenticated-orcid":false,"given":"Olga","family":"Vodyankina","sequence":"additional","affiliation":[{"name":"Laboratory of Catalytic Research, Tomsk State University, 36 Lenin Avenue, 634050 Tomsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117770","DOI":"10.1016\/j.apcata.2020.117770","article-title":"Selective hydrogenolysis of biomass-derived sorbitol to propylene glycol and ethylene glycol on in-situ formed PdZn alloy catalysts","volume":"603","author":"Jia","year":"2020","journal-title":"Appl.
