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 Ce1-xGdxO2-z(x = 0,1; 0,15; 0,2) samples in a model reaction of crystal violet dye photodecomposition.
Keywords: nanocrystalline cerium dioxide, solid solutions, photocatalytic activity, photoprotector properties.
