A simple method to controlled synthesis of CeO 2 hollow microspheres

CeO2 hollow microspheres have been 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 to 50 nm by adjusting the concentration of Ce(NO3)3 in the reaction solution. The high UV absorption of CeO2 hollow microspheres indicates that this material is suitable as a UV-blocking material.

Self-assemblage of Single/Multiwall Hollow CeO2 Microspheres through Hydrothermal Method

Abstract Novel single/multiwall hollow CeO2 microspheres were synthesized by self assemblage through hydrothermal method without any surfactant, the shells of which were consisted of CeO2 nanoparticles with mean size of 70 nm. The influence of the molar ratio of urea to Ce(NO3)3·6H2O on the morphology of the products was investigated and the formation mechanism of single/multiwall hollow CeO2 was proposed.
