一种新颖Fe^(3+)/TiO_2薄膜的制备及光催化性能研究

Preparation and photocatalytic properties of a novel Fe^(3+)/TiO_2 films

用溶胶-凝胶法制备了纳米Fe3+/TiO2,以琼脂糖为载体,采用水热法合成纳米Fe3+/TiO2的琼脂糖凝胶。以降解转移因子制药废水为反应模型,研究了纳米Fe3+/TiO2琼脂糖凝胶薄膜的紫外光照射的催化活性及薄膜的重复使用效果。结果表明,纳米Fe3+/TiO2薄膜光催化活性明显较粉体的强,且不易失活,再生性能好,薄膜重复使用5次以上,仍有明显的降解效果。

The nano Fe3＋/TiO2 was prepared by sol-gel method.The nano Fe3＋/TiO2 agarose gel was synthesized by hydrothermal method with agarose as carrier.The catalytic activity of UV irradiation and film reuse effect of nano Fe3＋/TiO2 agarose gel were researched with degradation transfer pharmaceutical wastewater as model.The results indicated that the catalytic activity of nano Fe3＋/TiO2 film was better than that of powder,and difficult to deactive.Films could reuse more than 5 times and still had good degradation effect.
