摘要: 本文采用一种简单的高温溶剂方法合成了新颖的凸多面体状AgCl半导体纳米材料。通过X射线衍射仪，扫描电子显微镜，漫反射光谱和紫外–可见分光光度计对材料的微观结构和光催化性能进行了表征。结果显示，所得到的凸多面体氯化银纳米材料在可见光区间显示了非常好的吸收，并在降解罗丹明B染料的过程中显示出高效的光催化活性。此外，我们对所制得的AgCl凸多面体的光催化稳定性也进行了探讨。
Abstract: Novel convex polyhedra-like AgCl nanoarchitectures were synthesized via a facile refluxing method in the polyoldiethylene glycol (DEG). The microstructure and photocatalytic properties of the prepared materials were characterized by X-ray diffraction, scanning electron microscope, diffuse reflectance spectroscopy and UV-visible spectrophotometry. Results show that the as-obtained AgCl nano-polyhedra could effectively increase the absorption of the photocatalysts from UV-light to visible light and show an obvious efficient photocatalytic activity for degradation of RhB dye. Besides, the stability of the product in organic dye photodegradation process was also investigated.
