Abstract

In this study, the photocatalytic degradation of textile dyes using ZnO-CdS/Pd nanocomposites synthesized via a hydrothermal approach was investigated. The nanocomposite was characterized using X-ray diffraction, FESEM, TGA, and TEM, and its photocatalytic activity was evaluated through degradation of birillant green dye under exposure to solar light. The results showed that the optimum mass of Pd/ZnO-CdS nanocomposite for efficient photodegradation was 0.4 g/L, with a degradation efficiency of 86.6%. Scavenging experiments revealed that hydroxyl and superoxide radicals played a significant role in the degradation of birillant green dye. Additionally, the study summarized some of the fundamental chemical and physical features of HO2/O-, H2O2, and OH radicals, as well as how nanoparticles interact with nanocomposites and metal ions. The findings suggest that ZnO-CdS/Pd nanocomposite has the potential to be used for the removal of organic contaminants from textile waste due to their improved photocatalytic activity.
