- Аннотация: The physicochemical properties of the surface of the Y0.1CexZr1-xO2-delta, La0.1Cex Zr1-xO2-d (x = 0.1-0.7), and Y0.1CexPr0.61O2-delta. complex oxide systems were studied using IR and X-ray photoelectron spectroscopies. An appreciable enrichment of the surface of the solids in rare-earth-metal cations (cerium or praseodymium) during the synthesis was revealed. While cations are uniformly spread over the surface of cerium-zirconium solid solutions, the Y(0.1)Ce(x)Zr(1-x)O(2-delta)surface is covered by the clusters or even a phase of praseodymia. Reductive treatment in hydrogen with subsequent reoxidation results in the segregation of cerium ions on the Y(0.1)Ce(0.3)Zr(0.6)O(2-delta)surface at a temperature as low as 770 K.
