摘要: Abstract Magnetic Fe3O4/SiO2/Bi2WO6 microspheres with photocatalytic properties have been synthesized using a silica layer for “bonding” (adhering Bi2WO6 to Fe3O4). The morphology, composition and magnetic of the composites were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, vibrating sample magnetometry, BET surface area analysis. activity material in decoloration aqueous rhodamine B (RhB) solution under visible light was evaluated. results showed that combined well Fe3O4/SiO2 nanoparticles. spherical shape, having mean size 2 μm. spent catalyst could be recycled only slight decline catalytic activity. It is envisaged stability, reusability, nature warrants its application photocatalysis.
