| 摘 要： | 悬浮态的光催化反应器相比固载的光催化反应器有更高的光催化效率。但是如何在光催化反应完成后使催化剂与水溶液的分离 ,成为了一个关键的问题。本研究采用溶胶 凝胶法将二氧化钛直接沉积在磁性颗粒的表面 ,制备出了磁载的光催化剂。这种催化剂在保留了磁性能具有可磁分离的基础上又具有很好的光催化降解效果。

| Abstract: | Photocatalysis with suspended photocatalyst is more efficient than that with supported photocatalyst. But the separation of suspended photocatalyst in water solution is a critical problem. In this research, nano-sized photocatalyst carried by magnetic particle is prepared by co-precipitation and sol-gel methods. This mixed catalyst shows good performances in both photocatalytical character and magnetic character. |
