摘要：

Sn-doped nano-Bi2WO6 photocatalyst has been synthesized by a hydrothermal route at 180 degrees C for 12 h. The as-prepared samples were characterized in details by SEM, EDS, XRD and UV-vis DRS technologies. The photocatalytic activities of obtained products were determined by photodegradation of Rhodamine B (RhB) under simulated solar light. Experimental results indicated that the tin doping evidently improved the photocatalytic activity of Bi2WO6. The possible reasons for higher photocatalytic efficiency of Sn-doped nano-Bi2WO6 than that of pure Bi2WO6 are mainly ascribed to the addition of Sn ions which could suppress recombination between photogenerated electrons and holes.
