Abstract: Ag/AgX photocatalysts，as the new photocatalysts，exhibited high photocatalytic activity for the degradation of organic pollutants under visible light irradiation due to the obvious surface plasmon resonance (SPR) effect in the visible light region. In this paper，the structure，mechanism，preparation methods and morphology of plasmonic Ag/AgX(X=Cl,Br,I) photocatalysts are reviewed. The applications of plasmonic Ag/AgX photocatalysts for the degradation of industrial dye wastewater are summarized and the trend of the plasmonic Ag/AgX(X=Cl,Br,I) photocatalysts for the degradation of high concentration and multi-component waste water is also discussed.

Key words: silver/silver halide (X=Cl,Br,I), plasmon, photocatalysis, dye wastewater

摘要： 银/卤化银[Ag/AgX（X=Cl,Br,I）]光催化剂作为一种新型光催化剂，由于在可见光区域具有明显的等离子共振效应从而显示了优异的可见光催化降解有机污染物的活性，引起了人们的极大重视。本文主要对Ag/AgX（X=Cl,Br,I）等离子体光催化剂的结构、光催化降解有机物机理、催化剂制备等进行了综述。Ag/AgX（X=Cl,Br,I）的活性普遍较高，通过半导体复合及形貌尺寸的控制，光催化性能得到进一步改善。进而论述了Ag/AgX体系等离子体共振光催化剂在工业染料废水处理上的应用现状，并对Ag/AgX（X=Cl,Br,I）等离子体光催化剂在高浓度、成分复杂污水体系处理中的应用进行了展望。
