CdS/TiO2 composite material was prepared by reverse-phase microemulsion method using cetyl trimethyl ammonium bromide（CTAB）,cyclohexane,n-butanol and water as main raw materials.The samples were characterized by field emission scanning electron microscopy（FESEM）,X-ray diffraction（XRD）,ultraviolet visible absorption spectrum（UV-Vis-Abs） and X-ray photoelectron spectroscopy（XPS）,respectively.The photocatalytic properties of the samples were studied with methyl orange as the target for degradation.The results show that cadmium sulfide has a significant effect on the surface morphology,crystalline composition,ultraviolet absorption band edge,element composition and chemical valence states of titanium dioxide.Compared with bare TiO2,the photocatalytic activity of CdS/TiO2 is significantly improved,and the sample of 3.3%CdS/TiO2 presents the best photocatalytic performance with a degradation rate of 96.71% for methyl orange under irradiation of 450 W gold halogen lamps for 80 min.The absorption band edge of TiO2 shows a certain blue shift after the compound.
