Sr6Bi2O9powders were synthesized by a sol–gel method using Bi(NO3)3·5H2O and Sr(NO3)2as the starting materials and were characterized by X-ray diffraction (XRD), UV–vis diffuse reflectance spectrum (UV–vis DRS), Fourier transform infrared (FT-IR) spectrum and Raman spectrum. The as-prepared Sr6Bi2O9powders showed an efficient photocatalytic activity in the decomposition of 4BS dye (a widely used azo dye) and 4-nitrophenol (4-NP, a priority pollutant) under visible light irradiation (λ>400nm). TA-PL analysis reveals that HO was not the dominant photooxidant. The radical scavengers experiments indicated that the main active species was O2−in the photocatalytic degradation of dye under visible irradiation. A possible photodegradation mechanism of organic pollutants by the visible light driven Sr6Bi2O9was discussed.
