摘要：Wetting chemical method is a common method for the preparation of nano-materials, which are useful for experimental study by undergraduate students. CeO2 hollow microspheres have been successfully synthesized by hydrothermal decomposition reaction of Ce(NO3)3 on the surfaces of silica microspheres. The shell thickness of CeO2 hollow microspheres can be controlled from 20 nm to 50 nm by adjusting the concentration of Ce(NO3)3 in the reaction solution. The morphologies of CeO2 hollow microspheres were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), field-emission scanning electron microscopy (FE-SEM).
