The CeO2 lattice is entered by Zirconium ,which will result in unequal M-O distances and oxygen vacancy (M for cerium or zirconium),  bring structure defects into the bulk,decrease the steric hindrance for  oxygen diffusing and promote the migration and  proliferation of oxygen in the bulk .

zirconium's entering into crystal lattice of CeO2 will cause unequal distance of  M-O and oxygen vacancy(M represents for Ce or Zr),consistently leading to structure defect in the bulk phase ,which decreases the spacial resistance of oxygen diffuse and improves the transfer and diffuse of oxygen in the bulk phase.
