摘要：

The flower-like microsphere Bi2WO6 with an average diameter of 2.5 μm is synthesized by a simple hydrothermal method in the presence of surfactant sodium dodecyl sulfate (SDS) or polyvinylpyrrolidone (PVP).The crystalline phase,compositions,morphology,microstructure,surface area and band gap energy of the Bi2WO6 are characterized by X-ray diffraction,X-ray energy-dispersive spectrum,scanning electron microscopy,transmission electron microscopy and absorption spectra.It is found that surfactant has a significant influence on the microstructure and properties of the samples.The surfactant SDS enhances the surface area and photocatalytic activity of Bi2WO6,while the surfactant PVP has an opposite effect.Under Xe lamp irradiation,the Bi2WO6 sample prepared in the presence of SDS can degrade dye Rhodamine B (RhB) effectively.
