Abstract Nano-BiOBr photocatalysts were successfully prepared by Microwave method using ethylene glycol solution. The nano-BiOBr photocatalysts were characterized and analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-visible diffuse reflectance spectroscopy (UV-Vis DRS), and the degradation ability of nano-BiOBr photocatalyst to adsorb rhodamine B (RhB) was also explored. The results show that the crystallinity of the nano-BiOBr photocatalyst increases with the increase of the concentration, and increases with increasing growth temperature. Nano-BiOBr microspheres of about two µm were polymerized by different self-assembly methods from nanosheets having a thickness of 10 nm to 15 nm. The concentration and growth temperature have an essential influence on the band gap of the nano-BiOBr photocatalyst. The degradation efficiency of photocatalyst decreases with the increase of concentration, increased with the increase in growth temperature. (e) photocatalyst showed the highest photocatalytic activity for RhB.

Nano-BiOBr光催化剂的微波法合成及光催化活性

摘要 利用乙二醇溶液通过微波法成功制备了纳米BiOBr光催化剂。通过X射线衍射(XRD)、扫描电子显微镜(SEM)和紫外-可见漫反射光谱(UV-Vis DRS)对纳米BiOBr光催化剂进行表征和分析,以及纳米BiOBr光催化剂对罗丹明的降解能力还探索了 B (RhB)。结果表明,纳米BiOBr光催化剂的结晶度随着浓度的增加而增加,随着生长温度的增加而增加。通过不同的自组装方法从厚度为 10 nm 至 15 nm 的纳米片聚合约 2 µm 的纳米 BiOBr 微球。浓度和生长温度对纳米BiOBr光催化剂的带隙有重要影响。光催化剂的降解效率随着浓度的增加而降低,随着生长温度的升高而增加。(e) 光催化剂对 RhB 显示出最高的光催化活性。
