Optical and Morphological features of CeO2 nanoparticles via facile co-precipitation method

Rare-earth metal oxide cerium oxide (CeO2) nanomaterials were prepared by facile coprecipitation process. The structural, morphological and optical properties of the prepared CeO2
samples are subjected to various characterization studies such as powder XRD, FTIR, SEM, TEM, UV and PL analysis. The powder XRD patterns showed the cubic fluorite phase of cerium oxide sample. The spherical-like morphology of CeO2 nanoparticles are observed from the SEM and TEM analysis with average crystallite size range of 15 nm. The photocatalytic activities of the cerium oxide samples were examined using an Amido Black dye, it showed the effective rare-earth metal oxide photocatalyst.
