A solution-processed cerium oxide (CeO2)-titanium oxide (TiO2) nanocomposite was utilized as an effective visible-light driven photocatalyst for the photodegradation of bromophenol (Bph) dye. The structural and the morphological properties revealed good interaction between CeO2 and TiO2 nanomaterials in CeO2-TiO2 nanocomposite. The CeO2-TiO2 nanocomposite showed enhanced optical properties with significant red shift after the addition of CeO2 nanoparticles. The CeO2-TiO2 nanocomposite as photocatalyst accomplished enormously high degradation of Bph-dye by similar to 72% within 3 h under visible-light illumination. The improved degradation might attribute to the higher adsorption capacity and the better (e) over bar -h(+) pair separation under light illumination. (C) 2014 Elsevier B.V. All rights reserved.
