| 摘 要： | 本文采用简便的水热法一步合成ZnS微米花,通过X射线衍射仪、扫描电子显微镜等表征手段研究了合成产物的形貌及微观结构,并考察了合成产物的光催化性质。合成产物的光催化测试结果表明,在紫外光辐照下,产物对亚甲基蓝、甲基橙和曙红都有很好的降解效果。为了测试产物循环利用的光催化能力,对其进行了5次降解实验,结果显示产物依然保持良好的光催化活性。

| Abstract: | ZnS microflowers have been synthesized by one step hydrothermal method. Morphologies and microstructures of the as-synthesized products were investigated by X-ray diffraction and Scanning Electron Microscope. At the same time, photocatalytic properties of the as-obtained products were also studied in detail. It showed that ZnS microflowers had excellent degradation efficiencies to methylene blue, eosin red and methyl orange under UV-light irradiation. Photocatalytic cycling experiment is done to study the stability and reusability of the photocatalyst by conducting cyclic reactions for five times for the photodegradation of MB,demonstrating that ZnS microflowers possess superior photocatalytic activity. |
