Cerium oxide possesses exceptional properties due to its abundant oxygen vacancy defects,high oxygen storage capacity and ability to relatively easily shuttle between Ⅲ and Ⅳ oxidation states[1].It has been extensively studied and employed in many applications,including three-way catalyst,photocatalyst,and electrolytes for solid oxide fuel cells.CeO2 nanoparticles have been synthesized using different methods.However,these materials often suffer from poor thermal stability.To solve the problem,studies have been focused on the morphology control and composition adjust.On one hand,CeO2 with morphologies has been prepared,such as nanorods,flower-like and hollow spheres.
