中文摘要：

卤代有机污染物（halogenated organic contaminants，HOCs）具有持久性强、难生物降解的特点，排放到环境后对生态安全及人类健康造成了巨大危害，在环境领域备受关注。负载型催化剂降解HOCs的反应条件温和易行，产物低毒易于降解或可重新作为原材料使用，成为环境污染化学降解技术研究的热点。本文综述了负载型催化剂降解HOCs的种类、反应机理和各种因素的影响机制，介绍了相关研究进展并讨论分析了该技术存在的问题，并提出了该技术的发展前景及今后重点研究方向。

英文摘要：

Due to their highly persistent and biorefractory property in environment, halogenated organic contaminants （HOCs） possess the potential risk to ecological safety and human health after released into our surroundings so that their problems have attracted much attention in the concerned researches. Reductive hydrodehalogenation （HDH） by supported catalyst provides the practicable approach to decontaminate HOCs with mild reaction conditions, which forms the low toxic products easily for biodegradation or to recycle as chemical raw materials. So it has been in the spotlight of study on chemical treatment method for environment pollution. This paper reviews the degradation categories, HDH reaction pathway of HOCs with supported catalyst as well as the influential mechanisms of various relative factors. It is also introduced for the progress on these studies and further discussions about some remaining problems in the development of the catalytic HDH technology. In addition, the future trends for this method are prospected.
