摘　　要：以钛酸丁酯为原料,采用溶胶—凝胶法制备了纳米TiO2,用XRD进行了测试分析,TEM观察粒径与形貌,并用该材料进行了光催化降解甲基橙溶液的实验。结果表明,纳米TiO2粉体粒度较小,为锐钛矿型,具有较好的光催化性能。Nano-TiO2 powder is prepared by the method of sol-gel with tetrabutyl titanate as raw material, The nano-particles are examined by means of X-ray Diffraction （XRD） and Transmission Electron Microscope （TEM）. The nano-TiO2 prepared above is used to degrade methyl orange by photocatalysis. The results show that anatase-type nano-TiO2 powder has a small size and a great photocatalystic effect.
