title: [The relationship between structure and oxygen storage capacity of Ce(x)Zr(1-x)O2 solid solution].
abstract: Heating reflux aging technology was applied to prepare a series of Ce(x)Zr(1-x)O2 (0.25 < or = x < or = 1) solid solution. The effects of the Ce(x)Zr(1-X)O2 composition on the structure and oxygen storage capacity were characterized using N2 physical adsorp tion, X-ray diffraction (XRD), FT-Raman, UV-Vis diffuse spectroscopy techniques. The texture, structure and thermal stability of ceria-zirconia mixed oxides are closely related to the ratio of cerium to zirconium in the solid solution, with increasing the zirconium content, the specific area increases, and the structure undergoes a change of order --> disorder --> order. Among them, Ce(0.4Zr(0.6)O2 sample possesses the maximum OSC and Ce(0.25)Zr(0.75)O2 sample possesses the best thermal stability.
