Preparation of Pt–MeOx system by oxidation of Pt–Mealloys


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.
