摘要：

In this work, we have successfully fabricated ternary Fe3O4/ZnO/CuWO4 nanocomposites with different weight percentages of CuWO4 by refluxing method. The visible-light photocatalytic activity of the Fe3O4/ZnO/CuWO4 nanocomposites was investigated using Rhodamine B. It was found that the photocatalytic activity of the nanocomposites significantly depends on the weight percentage of CuWO4. Among the prepared samples, the nanocomposite with 40% of CuWO4 displayed the highest activity. The superior photocatalytic ability of the Fe3O4/ZnO/CuWO4 (40%) nanocomposite compared to the binary Fe3O4/ZnO and Fe3O4/CuWO4 photocatalysts in degradation of methylene blue, as another organic dye, under visible-light irradiation was also confirmed.
