Preparation of Bi2WO6/Fe3O4 Composite and Photocatalytic Degradation of Bisphenol A
Bi2WO6/Fe3O4 nanocomposite materials with uniform morphology and size were successfully synthesized by hydrothermal method, and its catalytic degradation effect on bisphenol A was studied. The composite material was studied to analyze the microstructure and internal composition of the composite material by X-ray diffraction (XRD), energy dispersive X-ray spectrum (EDS), scanning electron microscope (SEM), transmission electron microscope (TEM) and other analytical methods. The degradation rate of BPA can be effectively controlled when the light is applied under the optimal conditions, the degradation rate of bisphenol A by the composite catalyst has reached 93.45% when the light duration lasts for 120 min. The composite material is a magnetic material, which combines the dual characteristics of the catalytic material and the magnetic material. It can not only catalyze the degradation of the target pollutant, but also recycle and reuse the magnetic material, it improves the utilization ratio of the material.
