Ag modified TiO2 nano-fiber was prepared by electrostatic spinning method.The basic physical properties of the nano-fiber were analyzed by XRD,TEM and UV-Vis and the photo-degradation effect of that on methylene blue solution was investigated under UV and floodlight irradiation.Physical properties analysis showed that the Ag modified TiO2 nano-fiber had a polycrystalline structure of anatase and rutile,and the absorption peak between 400 nm and 800 nm was enhanced by about 50%,indicating that the light absorption range of the Ag modified TiO2 nano-fiber was greatly expanded.The photo-degrada-tion analysis showed that the absorption peak of MB solution could be reduced to 0 after 120 min of UV irradiation,and the absorption peak of MB solution could also be reduced to below 0.1 after 120 min of floodlight irradiation,which indicated that the Ag modified TiO2 nano-fiber had better UV and floodlight degradation efficiency for MB.
