摘要：
Flower-like hierarchical Bi2WO6/ZnO nanostructures have been successfully obtained through the hydrothermal method. The composite is characterized by XRD, UV–Vis, SEM, EDS and XPS. The synthesized flower-like Bi2WO6/ZnO heterojunction photocatalyst can effectively degrade rhodamine (RhB) and methylene blue (MB). The photocatalyst degradation efficiency of MB can reach 96%, and the degradation efficiency of RhB can reach 92%. Recycle experiments show that Bi2WO6/ZnO maintains good photocatalytic activity and stability after five cycles of use. Through various characterizations, the photocatalytic mechanism was well explained and proved.
