英文摘要	In this paper, Cu2+ was successfully doped into Bi2WO6 to further promote the photocatalytic performance of Bi2WO6. The presence of Cu2+ in the lattice of Bi2WO6 can be confirmed by the results of X-ray diffraction (XRD), energy dispersive spectrometer (EDS), high-resolution transmission electron microscopy (HRTEM) and element mapping images. The results of surface photovoltage spectroscopy (SPS) show that doping Cu2+ into the lattice of Bi2WO6 can greatly boost the separation rate of photoinduced electron-hole pairs. The electron spin-resonance (ESR) and trapping investigation exhibit that center dot O-2 (-) is the main active free radicals. The photocatalytic performance of Cu-doped Bi2WO6 photocatalysts toward decolorization of rhodamine B (RhB) was evaluated under simulated sunlight irradiation using a 500 W Xe lamp as light source. Cu-doped Bi2WO6 photocatalysts display remarkably enhanced photocatalytic performance than the bare Bi2WO6, and when the molar ratio of Cu/Bi is 0.6%, the photocatalyst prepared displays the best photocatalytic activity.
