This paper explores the photocatalytic degradation of Reactive Orange 16 (RO16) dye in textile wastewater employing a novel CuO@A-TiO/Ro-TiO nanocomposite. The nanocomposite was synthesized via a hydrothermal technique, resulting in a monoclinic phase of leaf-shaped CuO loaded on a hexagonal wurtzite structure of rod-shaped ZnO, as confirmed by FE-SEM and XRD analyses. Optical experiments revealed band gap energies of 1.99 eV for CuO, 2.19 eV for ZnO, and 3.34 eV for the CuO@A-TiO/Ro-TiO nanocomposite. Photocatalytic degradation experiments showcased complete elimination of a 100 mg/L RO16 solution (150 mL) after 120 min of UV light illumination and 100 min of sunlight illumination, emphasizing the nanocomposite's efficiency under both light sources. The study further delves into the application of the CuO@A-TiO/Ro-TiO nanocomposite for the degradation of actual textile wastewater samples under sunlight irradiation. The results underscore the nanocomposite's remarkable efficacy in treating RO16 in textile wastewater, positioning it as a promising candidate for sustainable and efficient wastewater treatment applications. This research contributes valuable insights into the development of advanced photocatalytic materials for textile dye degradation in wastewater treatment.
本文研究了一种新型的CuO@A-TiO/Ro-TiO纳米复合材料对纺织废水中活性橙16（RO16）染料的光催化降解性能。通过水热法合成了该纳米复合材料，场发射扫描电子显微镜（FE-SEM）和X射线衍射（XRD）分析证实，其为负载在棒状ZnO六方纤锌矿结构上的单斜相叶状CuO。光学实验表明，CuO的带隙能量为1.99 eV，ZnO为2.19 eV，CuO@A-TiO/Ro-TiO纳米复合材料为3.34 eV。光催化降解实验表明，在紫外光照射120分钟和太阳光照射100分钟后，100 mg/L的RO16溶液（150 mL）被完全降解，这突出了该纳米复合材料在两种光源下的效率。该研究进一步探讨了CuO@A-TiO/Ro-TiO纳米复合材料在太阳光照射下对实际纺织废水样品的降解应用。结果强调了该纳米复合材料在处理纺织废水中RO16方面的显著效果，使其成为可持续高效废水处理应用的有前途的候选材料。这项研究为开发用于废水处理中纺织染料降解的先进光催化材料提供了有价值的见解。
