▎ 摘　　要

3D structured flower-like bismuth tungstate/magnetic-graphene nanoplates (Bi2WO6/mag-GNPs) composite was first synthetised for degradation of ciprofloxacin (CIP). The morphological properties of Bi2WO6/mag-GNPs were characterized by SEM, XRD and DRS. The results revealed the synthesized Bi2WO6/mag-GNPs had the enhanced photocatalytic activity because of the synergistic effects of Bi2WO6, graphene and Fe3O4. The photocatalytic degradation rate of Bi2WO6/mag-GNPs toward CIP was almost 6.0 times of mag-GNPs, 2.0 times and 1.7 times of Bi2WO6 and Bi2WO6/GNPs, respectively. Moreover, the Bi2WO6/mag-GNPs particles could be easily separated and recycled. The construction of Bi2WO6/mag-GNPs effectively resolved the separation of photocatalyst and improved the photocatalysis activity of Bi2WO6.
