摘　　要：以钛酸丁酯为原料,用溶胶-凝胶法制备了二氧化钛纳米材料。采用TEM和XRD对所制备的纳米材料进行了表征和分析。通过降解甲基橙对其光催化性能进行研究。结果表明,在紫外灯照射下,550℃下煅烧得到的粉体纳米TiO2光催化效果较好。Ti（OC4H9）4 was used as a raw material,and nanometer particles TiO2 were prepared by a sol-gel process.The nanometer particles TiO2 could be analyzed and characterized by XRD spectra and TEM.The photocatalytic activity of TiO2 could be studied through the degradation of methyl orange.The results showed that the sample calcined under 550℃,and the photocatalytic activity could be the best in these samples.
