Nanostructured Ceria Synthesized By Detonation Method And Its Ultraviolet Absorption Performance

Abstract

Nanostructured ceria particles have been successfully synthesized by detonation method with emulsion explosives. The effects of mass content of Ce(NO3)3·6H2O in emulsion explosives on particle size of CeO2 were investigated. X-ray diffraction (XRD) and Transmission Electron Microscope (TEM) were carried out to characterize as-synthesized powders. The ultraviolet absorption performance of nanostructured ceria was tested by ultraviolet spectrophotometer. The results indicated that the mass content of Ce(NO3)3·6H2O in emulsion explosives affected the particle size of ceria mostly. When the mass content of Ce(NO3)3·6H2O was 53.2%, the particle size of ceria was even and on the small side. The UV absorption performance of assynthesized nanostructured ceria was excellent, especially for ultraviolet B.
