Photocatalysis is considered as an ideal strategy for water pollution treatment. However, it remains challenging to design a highly efficient photo-catalytic system through regulating the charge flow via a precise approach. In this work, a novel NH2-MIL-125(Ti)/Bi2WO6 composite was constructed via self-assembly growing Bi2WO6 nanosheets on NH2-MIL-125(Ti) material. The characterization results demonstrated that NH2-MIL-125(Ti) was successfully incorporated into Bi2WO6 and the photoexcited carriers could be efficiently separated and transferred between the two components. NH2-MIL-125(Ti)/Bi2WO6 composites displayed enhanced photocatalytic activity for the removal of rhodamine B (RhB) and tetracycline (TC) under visible light irradiation, and the optimal weight ratio of NH2-MIL-125(Ti) was determined to be 7 wt％. The introduction of NH2-MIL-125(Ti) into Bi2WO6 could raise the absorption of visible light, accelerate the separation and transfer of charge carriers, and boost photocatalytic activity. This research presents a wide range of possibilities for the further development of novel composites in the field of environment purification.
