Abstract | A novel flower-like ternary Fe3O4-magnetic quantum dots / Bi2WO6/ Graphene nanosheet (Fe3O4− MQDs /Bi2WO6 / GNs) composite was successfully prepared by a facile one-pot hydrothermal method. The prepared samples were characterized by XRD, FTIR, UV–vis, SEM, HRTEM, EDS, BET and VSM technologies. Compared with the Bi2WO6 and Fe3O4/Bi2WO6, the Fe3O4/Bi2WO6/GNs catalyst exhibited higher photodegradation ratio of 98.2% for methylene blue (MB) and 90% for Tetracycline hydrochloride (TC) within 210 min irradiation at pH 7, and stability over 80% even after six cycles. Characterization results showed that the enhanced photocatalytic activity was mainly due to the strong interactions of MQDs/Bi2WO6heterojunction and high specific surface area. A possible photocatalytic degradation mechanism was proposed on the basis of the identified intermediates. Furthermore, the Fe3O4/ Bi2WO6/ GNs composite could be easily recovered from the reaction system under an external magnetic field owing to its sufficient magnetism, therefore which has certain potential applications in water treatment process. |
