Effect of morphology and size on the thermodynamic stability of cerium oxide nanoparticles: Experiment and molecular dynamics calculation

Abstract Cerium oxide nanoparticles have unique catalytic and oxygen storage capacity properties. In this work, the morphology size of cerium were experimentally theoretically investigated. For synthesis nanoparticles, laser ablation method was used. The analysis morphological characteristics performed using transmission electron microscopy. Using molecular dynamics, we reveal limiting dimensional transition from octahedral to a spherical form in nanoparticles. results obtained will be relevant for controlled nanostructured materials based on oxide.
