摘要：
The NiOx/Bi2WO6 photocatalyst with p-n heterojunction structure was synthesized. And the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-visible diffuse reflectance spectroscopy (UV-vis DRS). It was found that the RhB degradation rate with NiOx/Bi2WO6 was 1.62 times as great as that with the Bi2WO6 under visible light (lambda>400 nm) by the photocatalytic measurements. The enhanced photocatalytic performance of the NiOx/Bi2WO6 sample was attributed to the improved separation efficiency of photogenerated hole-electron pairs generated by the p-n heterojunction between Bi2WO6 and NiOx.
