摘　　要：本文以钛酸四丁酯为前驱体,通过调节溶胶至不同的pH,采用溶胶-凝胶法合成了锐钛矿型TiO2.通过X-射线粉末衍射仪(XRD)表征了其结构和组成,并在光照条件下,对所合成的典型的锐钛矿型TiO2样品,进行了光催化降解甲基橙性能研究.研究结果表明,在pH=5.0条件下制备的锐钛矿型TiO2光催化剂展示了较高的光催化性能.The anatase TiO2 photocatalysts were synthesized by using the sol-gel method with the tetrabutyl titanate as a precursor after the sol was adjusted to a desired pH value. And the structures of the obtained TiO2 photocatalysts were investigated by using X-ray diffraction(XRD). The photocatalytic activities of the typical anatase-type TiO2 photocatalysts were investigated by degrading the methyl orange. The experimental results show that the anatase-type TiO2 photocatalyst obtained at the value of pH = 5.0 exhibit the higher photocatalytic activity.
