摘要
用溶胶-凝胶方法制备TiO_2纳米膜,探讨了金属离子铁离子和贵金属Ag、Pt掺杂对TiO_2纳米膜光催化降解性能的影响。研究了TiO_2纳米膜及掺杂改性的TiO_2纳米膜对水杨酸的降解作用,同时还尝试光催化去除过滤后的生物二级处理系统出水中的有机物。实验结果表明TiO_2纳米膜有优良的光催化降解性能。
TiO2 nanofilm was formed by Sol-Gel method and modified on the photocatalysts by rare metal deposition such as Ag and Pt and Fe ion doping. The photocatalytic property was characterized by degrading salicylic acid and organic contaminant in reclaimed water. It's proved that TiO2 nanofilm has a good photocatalytic degradation property to the organic matters of the water. It's conformed that the technique of photo-catalytic degradation with TiO2 nanofilm would be extended widely in the future.
