Using only Ce(NO3)3\u00b76H2O in methanol\/water (MeOH\/H2O) mixtures without the addition of auxiliary templates or surfactants, phase-pure cubic CeO2 was obtained. Well-defined octahedra were exclusively formed in a 15 mL MeOH\/5 mL H2O system at 180 \u00b0C for 12 h, whereas other alcohols (including ethanol (EtOH), n-propanol (n-PrOH), and iso-propanol (i-PrOH)) yielded irregular aggregates. Time-dependent evolution revealed continuous crystallinity optimization between 3 and 24 h, beyond which surface dissolution occurred. The solvothermal mother liquor could be recycled four times without compromising phase purity or octahedral morphology, as confirmed by XRD and SEM. This work provides a green and practical route for morphology-controlled oxide synthesis while significantly reducing solvent consumption.<\/jats:p>","DOI":"10.3390\/nano16010053","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T16:34:23Z","timestamp":1767198863000},"page":"53","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Controlled One-Step Synthesis of Monodisperse CeO2 Octahedra in a Binary Solvent System with Waste Liquid Recycling"],"prefix":"10.3390","volume":"16","author":[{"given":"Yaohui","family":"Xu","sequence":"first","affiliation":[{"name":"Laboratory for Functional Materials, School of New Energy Materials and Chemistry, Leshan Normal University, Leshan 614000, China"},{"name":"Leshan West Silicon Materials Photovoltaic and New Energy Industry Technology Research Institute, Leshan 614000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Hu","sequence":"additional","affiliation":[{"name":"Laboratory for Functional Materials, School of New Energy Materials and Chemistry, Leshan Normal University, Leshan 614000, China"},{"name":"Leshan West Silicon Materials Photovoltaic and New Energy Industry Technology Research Institute, Leshan 614000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nengwei","family":"Zeng","sequence":"additional","affiliation":[{"name":"Laboratory for Functional Materials, School of New Energy Materials and Chemistry, Leshan Normal University, Leshan 614000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haimei","family":"Wang","sequence":"additional","affiliation":[{"name":"Laboratory for Functional Materials, School of New Energy Materials and Chemistry, Leshan Normal University, Leshan 614000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Laboratory for Functional Materials, School of New Energy Materials and Chemistry, Leshan Normal University, Leshan 614000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zongjie","family":"Liu","sequence":"additional","affiliation":[{"name":"Laboratory for Functional Materials, School of New Energy Materials and Chemistry, Leshan Normal University, Leshan 614000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinrui","family":"Chen","sequence":"additional","affiliation":[{"name":"Laboratory for Functional Materials, School of New Energy Materials and Chemistry, Leshan Normal University, Leshan 614000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1794-0392","authenticated-orcid":false,"given":"Zhao","family":"Ding","sequence":"additional","affiliation":[{"name":"National Engineering Research Center for Magnesium Alloys, College of Materials Science and Engineering, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"141253","DOI":"10.1016\/j.chemosphere.2024.141253","article-title":"The removal of toluene by thermoscatalytic oxidation using CeO2-based catalysts: A review","volume":"351","author":"Bai","year":"2024","journal-title":"Chemosphere"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"158832","DOI":"10.1016\/j.apsusc.2023.158832","article-title":"Superionic conduction of self-assembled heterostructural LSCrF-CeO2 electrolyte for solid oxide fuel cell at 375\u2013550 \u00b0C","volume":"645","author":"Meng","year":"2024","journal-title":"Appl.
