This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Magnetic Fe 3 O 4 /BiOI composite photocatalysts with visible light response were successfully fa-bricated through hydrothermal method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible diffuse reflection spectroscopy (UV-vis DRS) respectively. The characterization results show that the grain sizes of composite photocatalysts samples were varied from 0.5 μm to 2 μm and their morphologies were spheroid. The activities of composite photocatalysts with different proportions were evaluated by photodegradation of methyl orange under visible-light irradiation. Results show that the 5% Fe 3 O 4 /BiOI composite photocatalyst has the best photocatalytic activity. After 120 min of irradiation, removal rate of methyl orange reached to 81%, which was superior to the pure BiOI (40%). By the effect of the external magnetic field, the composite photocatalysts can be quickly and completely separated from the system, indicating a potential prospect in the practical application.
