Preparation
of Pt–MeOx system by oxidation of Pt–Mealloys
Abstract
Pt supported on molybdena and ceria were prepared by
oxidation of Pt–Mo and Pt–Ce alloys with different composition. Crystal
structure and phase composition of the samples before and after oxidation were
characterized by XRD. Morphology of the systems obtained was studied by SEM. It
was shown that oxidation of Pt–Mo alloys and Pt-Ce intermetallic compounds
leads to formation of Pt–MeOx systems containing nanosized Pt particles
supported on metal oxide. This preparation procedure can be used for synthesis
of Pt–MeOx with different metal oxides and sample composition.
