| Abstract: | In the paper, using butyl titanate as precursor and vesicles formed by anionic sodium dodecyl benzene sulfonate and cationic cetyl trimethyl ammonium bromide as soft temp - lates prepares the Titanium dioxide crystal. The properties of the sample were characterized by TEM, XRD, IR, UV - Vis. Analysis shows that the morphology of Titanium dioxide crystal is a rod , the size of Titanium dioxide crystal is about 90 -100nm and the crystal type of Titanium dioxide is anatase or rutile. The degradation rate of synthetic sample for reactive brilliant red under ultraviolet light reaches 82- 5%. |
