Abstract

The pulsed laser ablation (PLA) in alcohol and water media was employed to prepare Pt and CeO₂ PLA-nanoparticles of different sizes and degrees of defectiveness. Interactions of metallic platinum and ceria particles were studied using the thermal activation of Pt-CeO₂ mechanical mixtures in the CO+O₂ reaction medium or O₂ atmosphere. The thermal activation resulted in oxidized Pt²⁺/Pt⁴⁺ states of platinum in the surface solid solutions PtCeO_x and/or PtO_x clusters. Catalysts formed after calcination of the PLA-ablated Pt-CeO₂ mixtures in oxygen at 450-600°C revealed CO conversion at very low temperatures up to 70% depending on the conditions of PLA particles preparation and thermal activation of Pt-CeO₂ mechanical mixture.
