“…Cerium oxide (CeO 2 ) is a semiconductor with wide band gap energy (3.19eV). In the recent years, much effort has been made towards the development of new synthetic routes for preparing nanostructure cerium oxides due to their potential uses in many applications, such as high-storage capacitor devices, buffer layers for conductors, fuel cells, polishing materials, UV blocks and optical devices [1][2][3][4][5][6][7] . The cerium oxide nanoparticles are prepared by various methods [8][9][10][11][12] .…”

Cerium oxide (CeO 2 ) nanoparticles were prepared by the precipitation method. The average crystallite size of cerium oxide nanoparticles was calculated from the X-ray diffraction (XRD) pattern and found to be 11 nm. The FT-IR spectrum clearly indicated the strong presence of cerium oxide nanoparticles. Raman spectrum confirmed the cubic nature of the cerium oxide nanoparticles. The Scanning Electron Microscopy (SEM) analysis showed that the nanoparticles agglomerated forming spherical-shaped particles. The Transmission Electron Microscopic (TEM) analysis confirmed the prepared cerium oxide nanoparticles with the particle size being found to be 16 nm. The optical absorption spectrum showed a blue shift by the cerium oxide nanoparticles due to the quantum confinement effect. The dielectric properties of cerium oxide nanoparticles were studied for different frequencies at different temperatures. The dielectric constant and the dielectric loss of the cerium oxide nanoparticles decreased with increase in frequency. The AC electrical conductivity study revealed that the conduction depended on both the frequency and the temperature.

“…This method is especially effective when it is used to treat effluents that contain high levels of organic pollutants that are not easily degraded by other processes. As a result it is believed that the application of nanotechnology and nanomaterials to water treatment will provide solutions to many environmental problems [5][6][7].…”

“…Hollow CeO 2 microspheres have received considerable attention recently. Guo and coworkers [10] synthesized CeO 2 hollow microspheres with controlled shell thickness using silica microspheres as templates. The as-synthesized CeO 2 hollow microspheres exhibit strong absorption properties in the ultraviolet range.…”

Porous hollow CeO 2 microspheres were fabricated using negative-charged PS microspheres as templates by a facile method. The hollow CeO 2 microspheres were characterized by X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and N 2 adsorption-desorption. The results showed that the as-synthesized hollow CeO 2 microspheres are well monodisperse and uniform in size. The porous shells of hollow microspheres are relatively rough and composed of tiny nanoparticles. The external diameter, internal diameter, and shell thickness of hollow CeO 2 microspheres are about 190, 160, and 15 nm, respectively. A possible mechanism for the formation of hollow CeO 2 spheres was also discussed.
