本文首次采用一锅法水热合成了具有树枝状形貌的AgCl-Ag 2S纳米复合材料。使用AgNO 3、HCl和硫代乙酰胺作为起始试剂。采用X射线衍射、扫描电子显微镜、X射线能谱和紫外-可见漫反射光谱等技术对所制备的AgCl-Ag 2S纳米复合材料进行了表征。结果表明，纳米粒子自组装形成了树枝状的AgCl-Ag 2S纳米复合材料。研究了AgCl-Ag 2S纳米复合光催化剂在可见光照射下对橙子的脱色效果。结果表明，由于AgCl-Ag 2S纳米复合材料对更宽范围的光波长具有吸收能力，因此AgCl-Ag 2S纳米复合材料的光催化效率比AgCl纳米结构更高。
Herein, AgCl–Ag2S nanocomposites with dendritic morphology were synthesized via a simple one-pot hydrothermal route for the first time. AgNO3, HCl, and thioacetamide were utilized as starting reagents. The as-prepared AgCl–Ag2S nanocomposites were extensively characterized by techniques such as X-ray diffraction patterns, scanning electron microscopy, energy dispersive X-ray spectroscopy and diffused reflectance UV–visible spectrum. The results showed that the nanoparticles were self-assembled to prepare AgCl–Ag2S nanocomposites with dendritic morphology. The efficiency of AgCl–Ag2S nanocomposites as a photocatalyst for the decolorization of methyl orange (MO) using visible light irradiation has been evaluated. As a result, an enhanced photocatalytic efficiency of AgCl–Ag2S nanocomposites compared to AgCl nanostructures was obtained due to absorption of wider range of light wavelength by AgCl–Ag2S nanocomposites.
