Titania doped with 1-10 wt.% alumina was used as a thermostable support in the preparation of Pt/(Al2O3-TiO2) catalysts for the oxidation of CO. Pure titania (anatase) is metastable and irreversibly converts to rutile phase at 750 degrees C. However, in TiO2 doped with alumina, the temperature of the phase transition is above 950 degrees C. The stability of the anatase phase in Pt/(Al2O3-TiO2) catalysts at high temperatures ensures the maintenance of a high specific surface area and dispersion of platinum particles, which retain their high catalytic activity. This is due to the formation of a nanocrystalline structure of anatase in titania doped with alumina, unlike pure titania, in which a well-ordered regular anatase structure is formed.
