Abstract

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 ~72% within 3h under visible-light illumination. The improved degradation might attribute to the higher adsorption capacity and the better ē-h⁺ pair separation under light illumination.
