novel photo catalyst Ag-AgBr/TiO2 hetero structured nano fibers was fabricated by means of combiningsolvothermal technique with photo reduction method based on the electrospun TO2 nanofibers support.And, X-ray diffraction (XRD), X-ray photo electron spectroscopy (XPS), scanning electron microscopy(SEM), transmission electron microscopy (TEM), UV–vis spectrophotometer (UV–vis), and photolumi-nescence (PL) measurements were used to characterize the structure, morphology, and properties of theas-prepared photo catalysts. Further, the photo catalytic activity of photo catalysts was tested by degrad-ing methylene blue dye under visible light. As a result, the photo catalytic activity of the Ag-AgBr/TiO2 heterostructured nanofibers is far superior to that of TiO2 nanofibers and Ag-AgBr power, which could beattributed to the surface plasmon resonance effect of Ag nanoparticles and the synergetic effect between the three components of Ag, AgBr and TiO2. Significantly, the stability and recycling of the photocatalyst was also investigated. The possible mechanism related to the phot ocatalytic performance of theAg-AgBr/TiO2 hetero structured nano fibers was also gone deep into discuss.
