| 二氧化钛纳米管作为二氧化钛的一种重要形貌物质，在光催化降解有机污染物方面有着得天独厚的优势。特别是近几年来，许多研究小组通过二氧化钛纳米管的表面修饰改性以改善其对可见光吸收的利用率，在光催化降解有效去除有机污染物方面开展了大量的卓有成效的研究工作。众所周知，光催化剂有效光催化降解有机污染物的一个重要前提条件是催化剂表面与有机污染物的吸附，其中吸附量的大小以及吸附作用的快慢这两个因素将直接决定后续光催化降解效率的高低。另一方面，吸附本身作为一种去除污染物的有效手段，在水体中对污染物的分离与纯化发挥着至关重要的作用。因此，研究纳米光催化剂对有机污染物的吸附性能及其吸附机理，揭示光催化剂表面与有机污染物在光催化前的作用机制，对全面了解后续光催化机理以及如何筛选吸附性能好、光催化效果显著的新一代催化剂有着非常重要的研究价值。 |

Titanium dioxide nanotubes, as an important morphology of the titanium dioxide material, is of great advantage in the photocatalytic degradation of organic pollutants. Especially in recent years, a great deal of fruitful research was carried out by many research groups on the effective improvement of titania nanotubes by its surface modification to enhance the visible light absorption in the photocatalytic degradation of organic pollutants. As it's known to all, the most important prerequisite for the effective photocatalyst photocatalytic degradation of organic pollutants is adequate catalyst surface for adsorption of organic pollutants, in which the subsequent level of efficiency of photocatalytic degradation was greatly determined by the adsorption of the size and the speed of adsorption. On the other hand, adsorption itself, as an effective means of removing pollutants, play a crucial role for the separation and purification contaminants in the water. Therefore, the study on the adsorption of organic pollutants and their adsorption mechanism by photocatalyst agent by clarifing the role of catalyst surface and the action of light photocatalysis of organic pollutants in such mechanism, would generate a comprehensive understanding of catalytic mechanism and it is very important to know how to filter the light absorption properties, and significant effect of a new generation of photocatalytic catalysts. 仅供参考。  |
