摘　　要：沸石微孔晶体材料的比表面积较大、水热稳定性较高、微孔丰富均一以及表面性质可调,可用于吸附、催化、抗菌、药物输运和水处理。沸石的阳离子交换能力很强。在用离子交换法制备的载银沸石中,Ag主要以Ag+、银团簇和银纳米颗粒三种状态存在。Ag+良好的生物相容性以及银团簇高效和可调的发光性能,受到了极大的关注和深入研究。本文综述了通过离子交换法制备的载银沸石在白光LED以及可调多色发光荧光粉、传感器、抗菌材料、吸附和催化等方面的应用。Microporous crystalline zeolite materials have large specific surface area,high hydrothermal stability,abundant and uniform micropores and adjustable surface properties,which exhibited promising applications in adsorption,catalysis,antibacteria,drug delivery and water treatment.Zeolite has strong cation exchange ability and the Ag in silver-loaded zeolites prepared by ion-exchange method mainly exists in the following three states:Ag+,silver nanoclusters and silver nanoparticles.Due to the biocompatibility of Ag+and the efficient and adjustable luminescent performance of silver clusters,they have received wide attention in recent years.This article reviews the applications of silver-loaded zeolites prepared by ion-exchange method in white LEDs and tunable luminescent phosphors,sensors,antibacterial materials,adsorption and catalysis etc.
