Mesostructrured CeO2-TiO2 nanoparticles with different CeO2
contents have been successfully synthesized using ionic liquid (1-hexadecane-3-methylimidazolium
bromide. C16MIM+Br-) as a template by a hydrothermal method. The prepared materials were
characterized by means of X-ray diffraction (XRD), nitrogen adsorption-desorption, transmission
electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) and UV-vis diffuse reflectance
spectra analysis. The obtained CeO2-TiO2 materials exhibit large specific surface area and
uniform pore sizes. Introduction of CeO2 species can effectively extend the spectral response
from UV to visible area and enhance the surface hydroxyl groups of the mesoporous TiO2. The CeO2
-TiO2 nanocomposites show high photocatalytic activity in the degradation of the p-chlorophenol
aqueous solution under the UV or visible irradiation. (C) 2011 Elsevier B.V. All rights
