Abstract
The work is devoted to the structural study of doped Gd ceria–zirconia nanosystem by the EXAFS, WAXS (wide angle X-ray scattering) and XRD methods. A polymerized complex precursor method (Pechini route) was used for synthesis of ceria–zirconia doped by Gd. It was found by XRD analysis that samples of ceria–zirconia doped by Gd have a CeO 2 -reference structure (a cubic fluorite-like structure). However, analysis of the EXAFS and WAXS revealed the existence of two solid solutions with different content of zirconium cations, this implies heterogeneity on local level of structure.
