Silver clusters were introduced into the framework of zeolite Y. Low-temperature solid-state luminescence indicates the formation of silver–silver excimers and exciplexes that were found to be activated at 250 and 300 nm, respectively. The photodegradation of a persistent halogenated organic pollutant, namely 2,3,7,8-tetrachlorodibenzofuran (2,3,7,8-TCDF), was studied in the presence and absence of two catalysts, namely including AgY1 and AgY2, under mid- and high energy: 302 and 254 nm, respectively. The results showed that in the absence of a catalyst, degradation under 254-nm UV light resulted in changes to the peak intensity as well as energy, while the 302-nm profile showed only loss in peak intensity. In the presence of either catalyst, a higher rate of degradation of the 2,3,7,8-TCDF was observed. The amount of the adsorbed 2,3,7,8-TCDF on the AgY1 and AgY2 catalyst was estimated to reach 37.9 and 18.9% of its initial concentration, respectively. The toxicity of the intermediate and resultant products was further analyzed with the aid of an enzyme-linked immunosorbent assay. The optical density showed that in contrast to all the samples, the TCDF irradiated with 254 nm in the presence of AgY2 was high at 40 min inferring a decrease in toxicity of the resultant product. The present work shows an innovative and cost-efficient technique for the removal of dioxins and furans from water sources.

银团簇被引入到沸石Y的骨架中。低温固态发光表明形成了银-银准分子和激基复合物，分别在250和300 nm处被激活。在存在和不存在两种催化剂（包括AgY1和AgY2）的条件下，研究了一种持久性卤化有机污染物，即2,3,7,8-四氯二苯并呋喃（2,3,7,8-TCDF）的光降解。 -和高能：分别为302和254 nm。结果表明，在没有催化剂的情况下，在254 nm紫外光下降解会导致峰强度和能量的变化，而302 nm曲线仅显示峰强度的损失。在任何一种催化剂的存在下，观察到较高的2,3,7,8-TCDF降解速率。吸附量2,3,7，据估计，AgY1和AgY2催化剂上的8-TCDF分别达到其初始浓度的37.9％和18.9％。借助于酶联免疫吸附测定法进一步分析了中间体和所得产物的毒性。光学密度表明，与所有样品相比，在存在AgY2的情况下用254 nm辐照的TCDF在40分钟时较高，这导致所得产物的毒性降低。目前的工作显示了一种创新且具有成本效益的技术，用于从水源中去除二恶英和呋喃。光学密度表明，与所有样品相比，在存在AgY2的情况下用254 nm辐照的TCDF在40分钟时较高，这导致所得产物的毒性降低。目前的工作显示了一种创新且具有成本效益的技术，用于从水源中去除二恶英和呋喃。光学密度表明，与所有样品相比，在存在AgY2的情况下用254 nm辐照的TCDF在40分钟时较高，这导致所得产物的毒性降低。目前的工作显示了一种创新且具有成本效益的技术，用于从水源中去除二恶英和呋喃。
