摘　　要：以钛酸丁酯为前驱物,阴阳离子表面活性剂十二烷基苯磺酸钠（SDBS）/十六烷基三甲基溴化铵（CTAB）复配形成囊泡溶液,制备棒状二氧化钛纳米晶.并用TEM,XRD,IR,UV-Vis等分析方法对制备的二氧化钛纳米晶进行表征.结果表明,制备的二氧化钛纳米晶尺寸在90-110 nm之间,二氧化钛纳米晶为锐钛矿相和金红石相,合成样品在紫外光下对活性艳红降解率为82.5％.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%.
