摘要：

In this work, a magnetically separable polypyrrole (PPy) modified Fe3O4/ZnO composite photocatalyst was synthesized and its photocatalytic activity was tested. The as-prepared Fe3O4/ZnO/PPy nano-composite was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectra. Furthermore, three different photocatalysts including the Fe3O4/ZnO/PPy composite were tested using methyl orange (MO) degradation reaction under UV light irradiation. The relative results demonstrated that the Fe3O4/ZnO/PPy composite has the highest photochemical activity after 4 h photocatalytic experiment. It can be easily separated using an external magnetic field. This kind of composite photocatalysts with easiness of separation can have potential applications in the treatment of water contaminated by organic pollutants.
