Sn-doped nano-Bi2WO6 photocatalyst has been synthesized by a hydrothermal route at
180 °C for 12 h. The as-prepared samples were characterized in details by SEM, EDS, XRD and UVvis
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.
