Abstract
Cerium (IV) Oxide (CeO2) was synthesized by a wet chemical route and showed the formation of nanoparticles which were subject to a heterogenous agglomeration and generation of oxygen vacancies. These defects generated in ceria and in Ce-doped ZnO were found to have technological and environmental benefits in terms of photocatalysis and room-temperature magnetism. UV radiation was found to be a dominant factor in the performance of CeO2 and related materials, although hints of the workability of Ceria and its derivative in visible light were found. The morphological and structural changes occurring in the CeO2 during its growth were studied and correlated with the electronic and optical properties
