abstract = {The solid solutions CeO2–ZrO2 and CeO2–ZrO2–Y2O3 are
of interest for applications in industrial catalysis and
automotive exhaust purification and possess high oxygen
storage capacity. The reduction properties are greatly
influenced by the interaction of defects in the ceria host
lattice. The large number of different defects complicates
the description of these materials. In this study, the
interactions of defects in cerium oxide substituted with
zirconium oxide and yttrium oxide were investigated, both
for stoichiometric and nonstoichiometric composition, by
means of density functional theory and Monte Carlo
simulations. From the simulations, the impact of defect
interactions on the energy of reduction was obtained. In
agreement with experimental data, substitution with
zirconium oxide leads to a strong decrease of the energy of
reduction, which originated from the association between
oxygen vacancies and zirconium ions. Detailed analysis of
the calculated structures reveals pronounced local
relaxation as the origin of the strong association.},
