摘要：

Sulfur anion doped Zn2SnO4 was prepared by calcining the mixture of thiourea and spinel Zn2SnO4 at 300 degrees C under argon atmosphere and characterized by XRD, XPS and DRS. It was found that S2- was incorporated interstitially into the bulk phase of Zn2SnO4. After the doping of S2-, the band gap of Zn2SnO4 Was sharply decreased to 2.7 eV compared with that of uncloped Zn2SnO4 (-3.6 eV). The photocatalytic activity of S-doped Zn2SnO4 was enhanced for photoclegraclation of Rhodamine B (RhB) in aqueous solution under visible light irradiation. (C) 2009 Elsevier B.V.
