Novel AgBr/TiO
2 /(I/S) composite was synthesized by deposition–precipitation method. The AgBr/TiO2 /(I/S) composite was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectra, UV–Vis diffuse reflectance spectra and the N2 adsorption/desorption instrument. Under visible light irradiation, AgBr/TiO2 /(I/S) composite displayed much higher photocatalytic activity than that of pure I/S in the degradation of Rhodamine B (RhB). The RhB dye was degraded by 89% in less than 100 min. All results indicated that AgBr/TiO2 /(I/S) composite have good photocatalytic activity and chemical stability. Moreover, ·O2 − is demonstrated to be the dominant radical for the photocatalytic degradation of RhB. [ABSTRACT FROM AUTHOR]- Published
