摘要
采用玻璃弹簧为载体,以掺有纳米级Ti(OH)4粒子的溶胶-凝胶成膜,制备了可使光透射距离与普通玻璃微珠相比增加了5倍的嵌有纳米级TiO2粒子的光催化剂。其光降解模拟染料废水的脱色效率,与相同镀膜条件、相同质量的玻璃珠相比,提高了2.03倍。XRD图谱表明,在510℃时TiO2膜为锐钛矿相;SEM形貌像表明,掺入的纳米粒子均匀地镶嵌入TiO2薄膜中;DSC-TDG分析表明,507°C时Ti(OH)4分解失水且TiO2由无定型转变为锐钛矿相。
The glass spring used as a carrier,in a sol-gel containing nano-particle of Ti（OH）4,a photocatalyst embedded TiO2 nano-particles was prepared and it demonstrated five times of light transmission distance,compared with glass beads.The photocatalyst was tested the photo degradation efficiency on dye effluent decolorization.It increased 2.03 times than that of glass beads at the same deposition conditions.XRD patterns indicate that the TiO2 film is an anatase phase at 510 ℃.SEM micrographs show that the nanoparticles were evenly embedded into the TiO2 film.DSC-TDG analysis shows that the Ti（OH）4 phase decomposes,loses water,and transforms into an amorphous anatase phase at 507 ℃.
