Ag-基等离子体共振光催化剂的研究进展

摘要

Ag-based plasmon resonance photocatalysts attracted much attention because of their special physico chemical properties in the fields of photocatalytic decomposition of pollutants, water splitting, and biological sensor. Especially for the Ag/AgX（X =Cl,Br,I）, they became the hot topic of the visible-light responded pho- tocatalysis because of their high photocatalytic activity. In this review, the development of the Ag-based plas mon resonance photocatalysts in the recent years was summarised, and the photocatalytic reaction mechanism was discussed in detail. Ag-based plasmon resonance catalysts have the merits of simple preparation, low cost of raw materials, and high photocatalytic activity, so they will have a bright development prospect in the prati- cal photocatalysis.%Ag-基等离子体共振光催化剂因其特殊的物理化学性能,在光催化降解污染物、分解水和生物传感器等方面受到了广泛关注。尤其是Ag/AgX（X=Cl、Br、I）类等离子体光催化剂,由于其在可见光催化降解有机污染物中的优异表现,成为近年来可见光催化领域的研究热点。综述了近年来Ag-基等离子体共振光催化剂的研究进展,并深入探讨了其光催化反应机理。Ag-基等离子体共振光催化剂合成方法简单易行,原料成本低,光催化效率高,必将在应用光催化领域具有良好的发展前景。
