Abstract In this paper, we found that silver ions can efficiently degrade xanthene-based fluorescent dyes during the formation of Ag/AgCl nanoparticles under photo-assisted action. The experimental results indicates that both the ultraviolet absorption peak and fluorescence peak of xanthene-based fluorescent dyes disappeared in the presence of silver ions when the solution was irradiated with blue-violet light, implying the efficient degradation of these fluorescent dyes. Transmission electron microscopy (TEM) and Dynamic light scattering (DLS) analysis suggested the formation of nanoparticles during this process. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and STEM-mapping confirmed that the main chemical component of the nanoparticles was Ag/AgCl. To the best of our knowledge, it was the first time that the photo-assisted formation process of Ag/AgCl nanoparticles has been applied for the degradation of xanthene-based fluorescent dyes in a wide pH range (2.0–11.0) despite that Ag/AgCl nanoparticles are also widely used in dye degradation, and our experimental results also showed that the formation of photo-assisted Ag/AgCl nanoparticles is more efficient than Ag/AgCl nanoparticles themselves in dye degradation.

光辅助Ag/AgCl纳米颗粒形成工艺可用于荧光染料的降解

摘要 在本文中，我们发现银离子在光辅助作用下形成 Ag/AgCl 纳米粒子的过程中可以有效地降解呫吨基荧光染料。实验结果表明，当溶液用蓝紫光照射时，在银离子存在下，呫吨基荧光染料的紫外吸收峰和荧光峰均消失，表明这些荧光染料有效降解。透射电子显微镜 (TEM) 和动态光散射 (DLS) 分析表明在此过程中形成了纳米颗粒。X 射线衍射 (XRD)、X 射线光电子能谱 (XPS) 和 STEM 映射证实纳米颗粒的主要化学成分是 Ag/AgCl。据我们所知，
