Photo protector properties of ceria-based solid solutions

The studies concerning photocatalytic properties of nanocrystalline ceria and ceria-based materials appear to be controversial. Moreover, photocatalytic properties of nanocrystalline ceria-based solid solutions still remain unstudied. In this paper, we have performed synthesis and detailed study of nanocrystalline Ce$_{1-x}$Gd$_{x}$O$_{2-z}$(x = 0,1; 0,15; 0,2) samples in a model reaction of crystal violet dye photodecomposition.
