摘　　要：基于芬顿化学中产生的活性氧物种(ROS)具有强氧化能力,芬顿技术被广泛应用于环境、医学、离子检测、催化和有机合成等诸多领域。随着人们对环保、能源意识的日益增强,关于芬顿技术在多领域的应用研究也日趋深入。本文介绍了芬顿化学在环境污染物治理领域的应用,重点阐述了过渡金属及其化合物等芬顿催化剂的ROS产生机制、催化剂结构对于强化ROS产生的重要作用及调控ROS的构效关系,这对加深相关研究人员对芬顿技术在环境污染治理中的认识,为高效芬顿催化剂的设计和结构构建提供了有益的借鉴。最后,我们展望了芬顿化学面临的挑战和发展方向。With the progress of industrialization and urbanization,the problem of global water pollution is becoming more and more serious.More and more pollutants were discharged into water environment,especially the emerging contaminants such as drugs and rinse-off cosmetics.These pollutants are often organic compounds and most of them have the characteristics of high concentration,high complexity,high toxicity,refractory and so on,which have caused a great threat to human health.As one of the advanced oxidation technologies,Fenton technology can produce a variety of oxidizing reactive oxygen species(ROS),which is a potential and promising technology for the removal of organic pollutants in environmental water.With increasing awareness of environmental protection and energy conservation,the study on the application of Fenton technology has become more and more in-depth.Because of the rich variety and relatively large amount of ROS in reaction process,Fenton technology has been gradually applied in the fields of biomedicine,organic synthesis,analysis and detection.However,although researchers had made great achievements in Fenton chemistry,it still faced many challenges,such as the dispute over the formation mechanism of ROS,the inability to precisely regulate the types of ROS,the narrow application scope of catalysts,the lack of consensus on the principles of catalyst design,and so on.In particular,there was a lack of deep understanding for the structure-activity relationship between design principle of catalyst and ROS generation mechanism in Fenton chemistry.From the point of the removal of refractory organic pollutants in water environment,we focused on the mechanism of transition metals and their compounds as Fenton catalysts to produce ROS,as well as the important role of catalyst structure in enhancing the production of ROS.Firstly,the application of Fenton chemistry in environmental pollutants treatment,the types of ROS and the mechanism of ROS generation in Fenton chemistry were introduced.Hydroxyl radical,superox
