Abstract

In the present study, the nanocatalysts CeO₂, V ₂O₅, CuO, CeO₂/V₂O₅ and CeO₂/CuO were synthesized by thermal decompositionmethod. This method is simple, fast and cost effective comparedwith other preparationmethods. The synthesized catalysts were characterized by different techniques. The XRD and XPS results confirmed the structure and the oxidization states of the nanocomposite materials. DRS results suggested that the prepared CeO ₂/V₂O₅ and CeO₂/CuO nanocomposites can generate more electrons and holes under visible light irradiation. The photocatalytic activities of prepared catalysts were evaluated using the degradation of aqueous methylene blue solution as a model compound under visible light irradiation. In addition, the nanocomposite (CeO₂/V ₂O₅ and CeO₂/CuO) materials were employed to degrade the textile effluent under visible light condition.
