太阳光光催化降解水中有机污染物具有重要应用前景，是当前的研究热点和前沿课题之一。已见报道的许多光催化体系存在太阳能利用率低、太阳光光催化活性差和催化剂分离回收成本高的缺点，限制了光催化技术的实际应用。围绕提高光催化体系的能效和活性并解决催化剂难于回收等问题，本项目拟设计新型催化剂固定型光催化反应体系，该体系同时以光纤为铋系金属氧酸盐光催化剂的载体和光传输工具，将铋系金属氧酸盐优异的光催化性能与光纤独特的光传播方式相结合，可望提高光催化降解水中有机污染物总效率。通过模拟太阳光光催化降解水中典型环境激素研究，探索诸实验参数对负载在光纤表面的铋系金属氧酸盐光催化活性的影响规律，并揭示反应机理；通过研究光纤负载铋系金属氧酸盐的催化稳定性和循环使用情况，评价该体系的实际应用前景。本课题将环境科学与工程、光学和催化化学相融合，可望为太阳光光催化削减水中典型环境激素的实际应用提供重要基础研究数据。

Sunlight photocatalytic degradation of organic pollutants in wastewater has exhibited important application potential, and it is one of the research topics and pioneer projects. Disadvantages existed in most of the reported photocatalytic systems such as low sunlight utilization efficiency, poor sunlight photocatalytic activity, and difficulty for the catalyst separation limited the application of the photocatalysis. In this project, a novel immobilized photocatalytic reactor system will be designed for the purposes of improving sunlight utilization efficiency and sunlight photocatalytic activity as well as solving the catalyst separation problem. In this system, optical fiber bundles are used as both light transmission and catalyst support, and total photcatalytic efficiency of the degradation of aqueous organic pollutants is expected to be enhanced by the combination of superior light-energy utilization of bismuth-based oxometalate catalysts in the optical fiber photoreactor and excellent photocatalytic activity of the catalyst. In this system, influences of experimental factors on the simulated sunlight photocatalytic activity of bismuth-based oxometalates as well as the reaction mechanism are studied by the degradation of aqueous typical environmental endocrines; meanwhile, the practical application of the system is evaluated through studies on the catalytic stability and reusability of bismuth-based oxometalates coated on the optical fiber bundles. It is expected to provide important fundamental data for the practical application of sunlight photocatalytic degradation of aqueous typical environmental endocrines through the combination of environmental science and engineering, optics, and catalysis.
