Title: Atomic-scale structure of nancrystalline CeO{sub 2}-ZrO{sub 2} oxides by total x-ray diffraction and pair distribution function analysis.

Abstract

Total x-ray diffraction and atomic pair distribution function analysis have been used to determine the atomic ordering in nanocrystalline ({approx}1.5 nm in size) CeO{sub 2}-ZrO{sub 2} prepared by a sol-gel route. Experimental data show that the oxides are a structurally and chemically inhomogeneous mixture of nanoscale domains with cubic-type and monoclinic-type atomic ordering, predominantly occupied by Ce and Zr atomic species, respectively. The study is another demonstration of the great potential of non-traditional crystallography in studying the structure of nanocrystalline materials.
