Background and Aim: Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant organic dyes from industrial and municipal wastewater. So, the aim of this study was to evaluate the degradation of reactive black 5 using ZnO ZnO-CuO nano composite as a catalyst in the presence of UV light. 
Material and Methods: This research was an experimental study and performed at laboratory scale. The nanocomposite was characterized by scanning electron microscope) SEM). The effects of parameters on the photocatalysis process such as initial dye concentration, photocatalyst dose and pH were also studied. 
Result: Results showed that the degradation rate decreases as the initial reactive black5 (RB5) concentration increases. Also photocatalyst dose and pH results showed that the degradation efficiency of RB5 was carried out effectively at an initial pH 5 and photocatalyst dose 1.2 respectively, while increasing the pH and photocatalyst dose causes a decrease of the removal rate. 
Conclusion: It could be concluded that the photocatalytic process of ZnO-CuO/UV nanocomposite could be suitable technique for degradation of dyes and environmental pollution from effluents.
