In this work, spent coffee grounds were valorized by their utilization as a template for the synthesis of Ce\u2010loaded TiO\n                    <jats:sub>2<\/jats:sub>\n                    to be used as photocatalysts. The synthesis in the presence of the bio\u2010derived sacrificial template in the absence of solvent promote a hierarchical porosity and surface area and an intimate contact between Ce and Ti precursors to improve the photocatalytic activity of the obtained composite material. Pure TiO\n                    <jats:sub>2<\/jats:sub>\n                    is made up of nanoparticles that organize into fairly uniform spherical agglomerates of ca. 1\u2009\u03bcm. When Ce is introduced, this ordered structure gradually changes giving rise to less regular larger aggregates, and at higher loadings (5% Ce) the spherical morphology is no longer observed. In all cases a mesoporous structure is present. The activity of the obtained solids as photocatalysts was tested in three different reactions: (i) the photo reforming of ethanol in aqueous suspension of the photocatalysts in the absence of oxygen, to obtain hydrogen; (ii) the 2\u2010propanol oxidation in gas\u2013solid regime, and (iii) the 5\u2011hydroxymethylfurfural (5\u2011HMF) oxidation in aqueous suspension of the solids.\n                  <\/jats:p>","DOI":"10.1002\/open.70293","type":"journal-article","created":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T06:07:28Z","timestamp":1790057248000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cerium\u2010Modified TiO\n                    <sub>2<\/sub>\n                    Nanomaterials Derived From Upcycled Coffee Ground Waste for Photocatalytic Oxidation and Hydrogen Production via Photoreforming"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5403-5271","authenticated-orcid":false,"given":"Narimene","family":"Aoun","sequence":"first","affiliation":[{"name":"Department of Engineering University of Palermo  Palermo Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1409-8921","authenticated-orcid":false,"given":"Elisa I.","family":"Garc\u00eda\u2010L\u00f3pez","sequence":"additional","affiliation":[{"name":"Department of Engineering University of Palermo  Palermo Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5548-1783","authenticated-orcid":false,"given":"Bartolomeo","family":"Megna","sequence":"additional","affiliation":[{"name":"Department of Engineering University of Palermo  Palermo Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Aliotta","sequence":"additional","affiliation":[{"name":"Istituto per lo Studio dei Materiali Nanostrutturati (ISMN)\u2010CNR  Palermo Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeria La","family":"Parola","sequence":"additional","affiliation":[{"name":"Istituto per lo Studio dei Materiali Nanostrutturati (ISMN)\u2010CNR  Palermo Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ganna","family":"Kovtun","sequence":"additional","affiliation":[{"name":"Group of Nanotechnology and Materials Mining and Industrial Engineering School of Almad\u00e9n University of Castilla\u2010La Mancha  Almad\u00e9n Spain"},{"name":"V.G.
