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.
