Photocatalysis is applied increasingly in addressing and solving environmental and energy-related problems. Especially the TiO₂-derived catalysts attract attention because of their catalytic efficiency, wide range of applications, ease in use, and low cost (it costs about 150 Yuan a kilogram in China). This review first describes the principles of photocatalytic destruction by semiconductors and then focuses on degradation rates and reaction mechanisms in a variety of photocatalytic uses of modified TiO(2). Finally, these concepts are illustrated by selected examples relating to the photocatalytic degradation of organic persistent pollutants, such as polychlorinated benzenes (PCBz), biphenyls (PCB) and dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). And some approaches towards industrial application are analyzed.
光催化在解决环境和能源相关问题方面的应用越来越广泛。特别是 TiO₂ 衍生的催化剂因其催化效率高、应用范围广、使用方便和成本低（在中国的价格约为每公斤 150 元）而受到关注。本综述首先描述了半导体光催化破坏的原理，然后重点介绍了各种改性 TiO(2)光催化用途中的降解速率和反应机制。最后，通过与光催化降解有机持久性污染物（如多氯联苯 (PCBz)、联苯 (PCB)和二苯并-p-二恶英和二苯并呋喃 (PCDD/Fs) 有关的一些实例来说明这些概念。并分析了一些工业化应用的方法。
