摘　　要：芬顿与类芬顿氧化技术能够活化H_(2)O_(2),产生强氧化性的羟基自由基(·OH),可对绝大多数污染物彻底氧化.相较于其他类芬顿催化剂,以零价铁为代表的零价金属材料具有更优的理论电子供给潜力,活化H_(2)O_(2)能力突出,在污水治理领域被重点关注.本文综述了近年来零价金属类芬顿催化材料的研究进展,系统分析了铁基、铜基、钴基以及合金等零价态金属的反应机理和降解特点,并从异相催化角度探讨了类芬顿氧化处理废水的作用机制和催化剂性能提升策略.最后,对未来零价金属类芬顿催化材料的发展前景进行了展望.Fenton and Fenton-like oxidation technologies can activate H_(2)O_(2) and produce strong oxidizing hydroxyl radicals(•OH)for completely oxidizing most pollutants.Compared with other Fenton-like catalysts,zero-valent metal materials represented by zero-valent iron have better theoretical electron supply capacity to activate H_(2)O_(2),which have attracted much attention in the field of water purification.This paper reviews the research progress of zero-valent metal Fenton-like catalysts in recent years,and analyzes systematically the reaction mechanisms and degradation characteristics of zero-valent metals such as Fe-based,Cu-based,Co-based and alloy materials.Furthermore,the effect behaviors and improvement strategy of Fenton-like oxidation for wastewater treatment are discussed from the perspective of heterogeneous catalysis processes.At last,the future development of zero-valent metals Fenton-like catalytic materials is prospected.
