A PVP-stabilized cerium oxide-platinum nanocomposite synthesized in TEG: pro-/antioxidant activities.

ABSTRACT: Cerium oxide nanoparticles (CeNPs) represent a highly promising material for a number of chemical and biological applications involving oxidation-reduction processes. However, the impact of synthesis conditions, as well as the incorporation of synergistic agents of a different catalytic nature, on the antioxidant or prooxidant properties of CeNPs remains a subject of ongoing investigation. In this study, non-stoichiometric CeNPs (∼10% Ce³⁺) stabilized by polyvinylpyrrolidone (PVP) were synthesized through the thermal autoxidative decomposition of cerium(iii) nitrate in a high-boiling glycol. A novel approach for the synthesis of CeNPs in the absence of additives (PVP-CeNPs) and with platinum (PVP-CeNPs-Pt), followed by the formation of platinum nanoparticles (PVP-PtNPs), was emp
