The reactivity of some CeO2/YSZ nanocomposite catalysts towards the CO oxidation was investigated. The nanocomposite powders were prepared depositing, by wet impregnation, different amounts of CeO2 on the yttria-stabilized zirconia (YSZ) surface. Transmission Electron Microscopy analysis reveals that CeO2 grows as 3-D nanodimensional islands (ca. 4 nm) on the surface of the supporting YSZ. The reactivity of the nanocomposite systems towards the CO oxidation rapidly raises with increasing the amounts of CeO2 deposited on the YSZ.

Abstract
The reactivity of some CeO2/YSZ nanocomposite catalysts towards the CO oxidation was investigated. The nanocomposite powders were prepared depositing, by wet impregnation, different amounts of CeO2 on the yttria-stabilized zirconia (YSZ) surface. Transmission Electron Microscopy analysis reveals that CeO2 grows as 3-D nanodimensional islands (ca. 4 nm) on the surface of the supporting YSZ. The reactivity of the nanocomposite systems towards the CO oxidation rapidly raises with increasing the amounts of CeO2 deposited on the YSZ.File in questo prodotto:
