| 摘 要： | 以Ag NO3和反渗透水(RO)中的Cl–为原料,在波长为395 nm的紫外光源(20 W)下原位合成Ag/Ag Cl纳米颗粒。通过透射电子显微镜(TEM)、高分辨率的透射电镜(HRTEM)和动态光散射(DLS)表征了样品的形貌和尺寸分布,用X射线粉末衍射(XRD)、X射线光电子能谱(XPS)、紫外-可见吸收光谱(UV-Vis)和荧光光谱分别对复合材料的晶体结构和元素价态以及光催化性能进行了测试。结果表明:Ag/AgCl复合材料是球形颗粒,平均粒径为100 nm。AgNO3溶液形成复合纳米颗粒的过程能有效降解罗丹明6G,银离子溶液在光照3 min时罗丹明6G的降解率和猝灭率分别可达96.5%和95%。

| Abstract: | Ag/AgCl nanoparticles were synthesized in situ under 395 nm UV light with Cl- in reverse osmosis water (RO) and AgNO3 as raw materials. The morphology and size distribution of the samples were characterized by transmission electron microscopy (TEM) and dynamic light scattering (DLS).The crystal structure, element valence and photocatalytic performance of the composite were characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), ultraviolet-visible absorption spectra (UV-Vis) and fluorescence spectra separately. The results show that the Ag/AgCl composite are spherical particles with an average size of 100 nm. At the same time, the formation process of composite nanoparticles can effectively degrade rhodamine 6G. The degradation rate and quenching rate of rhodamine 6G can reach 96.5% and 95% when the silver ion solution was irradiated 3 min. |
