负载型改性TiO_2光降解亚甲基蓝研究进展
|
摘要
亚甲基蓝是印染行业常用的一种阳离子染料,每年产生的大量染料废水不仅破坏了水体环境甚至会引起人类"三致"(致畸、致癌、致突变)。TiO_2光催化技术具有低能耗、操作简单、彻底解决有机污染物等优点,但直接使用存在TiO_2与水分离难、重复利用率低等问题。而负载型改性TiO_2不仅可解决上述问题,且可借助载体比表面积大、孔隙率高的特点提高光催化速率和效率。介绍了近年来矿物材料、碳(炭)材料等负载型改性TiO_2复合光催化剂的制备及其对亚甲基蓝光催化降解的效果,指出负载型TiO_2光催化剂未来的发展方向。
Methylene blue is a kind of cationic dye usually used in dyeing and printing industry.Due to the endanger to the water environment and the harmful influence on human being,its wastewater must be treated carefully.Titanium dioxide has become the most promising photocatalyst in environmental field for its low-energy consumption,simple operation,the complete degradation of organic pollutants during the past years.However,the direct usage of TiO_2 particles can result in the difficulty separation and the lower reuse efficiency.The supported modified TiO_2 has high specific surface area and high porosity,thus its application in wastertater can resolve the above questions and improve the photocatalytic efficiency.The development on the preparation and effect of supported modified TiO_2 on the photocatalytic degradation of methylene blue in wastewater were reviewed and the future research trend was also pointed out.
