In this study, zinc oxide nanorods, hollow copper oxide microspheres, and ZnO/CuO nanocomposites were synthesized by a simple template-free precipitation technique. The synthesized photocatalysts were characterized by various techniques such as X-Ray powder diffraction (XRD), scanning electron microscopy (SEM), Uv-visible spectroscopy, diffuse reflectance spectroscopy (DRS), energy-dispersive X-ray spectroscopy (EDX). The potential of the obtained photocatalysts in the degradation of methylene blue and 4-nitro phenol was investigated under LED light irradiation. Results revealed that the photocatalytic activity of ZnO/CuO nanocomposites was higher than the photocatalytic activity of the ZnO and CuO under LED light irradiation

在这项研究中，通过简单的无模板沉淀技术合成了氧化锌纳米棒、中空氧化铜微球和 ZnO/CuO 纳米复合材料。通过X射线粉末衍射（XRD）、扫描电子显微镜（SEM）、紫外可见光谱、漫反射光谱（DRS）、能量色散X射线光谱（EDX）等多种技术对合成的光催化剂进行表征。在 LED 光照射下研究了所得光催化剂在降解亚甲蓝和 4-硝基苯酚中的潜力。结果表明，在 LED 光照射下，ZnO/CuO 纳米复合材料的光催化活性高于 ZnO 和 CuO 的光催化活性。
