One-pot hydrothermal fabrication of BiVO4/Fe3O4/rGO composite photocatalyst for the simulated solar light-driven degradation of Rhodamine B
文献摘要：
Fabrication of easily recyclable photocatalyst with excellent photocatalytic activity for degradation of organic pollutants in wastewater is highly desirable for practical application.In this study,a novel ternary magnetic photocatalyst BiVO4/Fe3O4/reduced graphene oxide(BiVO4/Fe3O4/rGO)was synthesized via a facile hydrothermal strategy.The BiVO4/Fe3O4 with 0.5 wt％of rGO(BiVO4/Fe3O4/0.5％rGO)exhibited superior activity,degrading greater than 99％Rhodamine B(RhB)after 120 min solar light radiation.The surface morphology and chemical composition of BiVO4/Fe3O4/rGO were studied by scanning electron microscopy,X-ray diffraction,X-ray photoelectron spectroscopy,UV-visible diffuse reflectance spectroscopy,Fourier transform infiared spectroscopy,and Raman spectroscopy.The free radicals scavenging experiments demonstrated that hole(h+)and superoxide radical(O2·-)were the dominant species for RhB degradation over BiVO4/Fe3O4/rGO under solar light.The reusability of this composite catalyst was also investigated after five successive runs under an external magnetic field.The BiVO4/Fe3O4/rGO composite was easily separated,and the recycled catalyst retained high photocatalytic activity.This study demonstrates that catalyst BiVO4/Fe3O4/rGO possessed high dye removal efficiency in water treatment with excellent recyclability from water after use.The current study provides a possibility for more practical and sustainable photocatalytic process.
