半导体和表面吸附的天线分子（染料或其他有色物质）可以构成有效的光化学系统，用于环境修复。这些系统的主要优点是，在环境条件下，它们能够通过使用来自太阳的可见光作为能量和空气中的O2作为氧化剂来实现有机污染物的降解。在本教程综述中，介绍了独特的机械特性，光降解系统的组成及其性能。并对降解过程中涉及的自由基反应进行了讨论。
The semiconductor and the surface-adsorbed antenna molecule (dyes or other color species) can constitute efficient photochemical systems for environmental remediation. The major advantage of these systems is that they are able to achieve the degradation of organic pollutants by using visible light from the sun as energy and O2 in the air as the oxidant under ambient conditions. In this tutorial review, the unique mechanistic characteristics, the constitution of photodegradation systems and their performance are described. The involved radical reactions during the degradation are also discussed.
