摘要：

Large-scaled uniform Y-doped ceria nanoparticles and nanorods were synthesized via room-temperature aging and hydrothermal treatments of high-temperature precipitates, respectively. The influence of Y content and morphology of the Y-doped ceria powders on the solid solution properties was studied. The specific surface areas (S-BET) of both the nanoparticles and nanorods were greatly enhanced by Y-doping, and the highest S-BET was 197 m(2).g(-1) in 30 mol% Y-doped ceria nanoparticles. Moreover, the as-prepared powders could be easily sintered and densified, and the corresponding electrolyte possesses good electrical properties, Y0.3Ce0.7O1.85 nanoparticles electrolyte has a maximum total electrical conductivity (4.32 S.m(-1)) and minimum apparent activation energy (0.81 eV) at 850 degrees C.
