| Abstract: | One-dimensional TiO2,for its large surface area and high aspect ratio,not only can play fully photocatalytic role of TiO2 in the industrial wastewater treatment,but also is easy to be separated,so the research on it has significant value.In this paper,the optimum condition to obtain TiO2 nanorods is determined.Then the phase and morphology of TiO2 are characterized by means of XRD、SEM、FT-IR、TGA-DSC.TiO2 appears in a form of nonarod,and belongs to anatase.Use of UV degradation of methyl orange is employed to examine the effect of photocatalytic activity of the TiO2 nanorods.The results show that compared with the degradation rate of sol-gel TiO2 powder the degradation rate of TiO2 nanorods increased about 10%. |
