In this article, the spherical filler-like ZnFe2O4/Bi2MoO6 (ZFO/BMO) surrounded by nanosheets were synthesized by a solvothermal method using spherical ZnFe2O4 as a matrix. Scanning electron microscope (SEM), X-ray diffraction (XRD), Photoluminescence (PL), Fourier transform infrared spectroscopy (FT-IR) and Diffuse reflectance spectra (DRS) were used to characterize the prepared samples. The photocatalytic performance of the material was detected under 420 nm visible light by Rhodamine B (RhB). The degradation results indicated that the ZFO/BMO photocatalyst with 20% ZnFe2O4 content (ZFO/BMO-2) demonstrated highly efficient performance. The constructed Z-type ZFO/BMO heterojunction lengthens the visible light absorption threshold and improves the photocatalytic activity. Furthermore, ZFO/BMO heterojunction composite photocatalyst can be recycled effectively by applying an appropriate external magnetic field. It has important research value in photocatalysis and recycling.
