Experimental observations suggest that exposing ceria-supported Pt nanoparticles to O₂ at 500 °C promote their dispersion into smaller particles and eventually single atoms. In the associated paper we have combined several approaches and types of models in a consistent atomistic framework to evaluate the relative stability of ceria-supported Pt as a function of the degree of oxidation of Pt and of the particle size, ranging from single atoms to nanoparticles of 1.5 nm of diameter.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2024.17</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:sw-3c</dc:identifier> <dc:identifier>mcid:2024.17</dc:identifier> <dc:identifier>oai:materialscloud.org:2063</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode</dc:rights> <dc:subject>Platinum</dc:subject> <dc:subject>Cerium oxide</dc:subject> <dc:subject>DFT+U</dc:subject> <dc:title>The role of oxidizing conditions in the dispersion of supported platinum nanoparticles explored by ab initio modeling</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
