Full conversion and selectivity between 38 and 68% to sodium glycerate were observed on different Au supported catalysts (Au\/MgO\/TiO2, Au\/La2O3\/TiO2, Au\/CeO2 and Au\/CeO2\/TiO2). The combined effect of Au particle size and basicity of the support was suggested as the determining factor of the activity. Agglomeration of gold nanoparticles, found after the reaction, led to the deactivation of the catalysts, which prevents the further oxidation of sodium glycerate into sodium tartronate. Promising results were obtained with the use of alkaline earth bases (CaO, SrO, MgO), leading to the formation of free carboxylic acids instead of salts, which are formed in the presence of the more usual base, NaOH.<\/jats:p>","DOI":"10.3390\/pr8091016","type":"journal-article","created":{"date-parts":[[2020,8,20]],"date-time":"2020-08-20T21:13:42Z","timestamp":1597958022000},"page":"1016","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Glycerol Oxidation over Supported Gold Catalysts: The Combined Effect of Au Particle Size and Basicity of Support"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2842-2542","authenticated-orcid":false,"given":"Ekaterina","family":"Pakrieva","sequence":"first","affiliation":[{"name":"Research School of Chemistry &amp; Applied Biomedical Sciences, National Research Tomsk Polytechnic University, Lenin Av. 30, 634050 Tomsk, Russia"},{"name":"Instituto de Cat\u00e1lisis y Petroleoqu\u00edmica, Consejo Superior de Investigaciones Cient\u00edficas, Marie Curie 2, 28049 Madrid, Spain"}]},{"given":"Ekaterina","family":"Kolobova","sequence":"additional","affiliation":[{"name":"Research School of Chemistry &amp; Applied Biomedical Sciences, National Research Tomsk Polytechnic University, Lenin Av. 30, 634050 Tomsk, Russia"}]},{"given":"Dmitrii","family":"German","sequence":"additional","affiliation":[{"name":"Research School of Chemistry &amp; Applied Biomedical Sciences, National Research Tomsk Polytechnic University, Lenin Av. 30, 634050 Tomsk, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0711-3684","authenticated-orcid":false,"given":"Marta","family":"Stucchi","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica, Universit\u00e0 degli Studi di Milano, via Golgi 19, 20133 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8656-6256","authenticated-orcid":false,"given":"Alberto","family":"Villa","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica, Universit\u00e0 degli Studi di Milano, via Golgi 19, 20133 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8227-9505","authenticated-orcid":false,"given":"Laura","family":"Prati","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica, Universit\u00e0 degli Studi di Milano, via Golgi 19, 20133 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9913-4671","authenticated-orcid":false,"given":"S\u00f3nia.
