| 摘 要： | 以β-环糊精(β-CD)、硝酸铋、溴化钾为原料,采用溶剂热法合成了银耳状BiOBr.通过X射线衍射(XRD)、扫描电镜(SEM)和紫外可见光谱(UV-Vis)对BiOBr粒子进行表征.实验发现:BiOBr的微观形貌与β-CD的用量有关,当β-CD的用量为0.4574 g时,所制得的BiOBr为银耳状,且其光催化性能最好.

| Abstract: | A solvothermal method to prepare tremella-like BiOBr was developed by using β-CD, Bi(NO3)3·5H2O and KBr as starting materials. The nano BiOBr was characterized by X-ray diffraction, scanning electron microscopy(SEM) and UV-visible. It was found that the micro-morphology of BiOBr was greatly influenced by the amount of β-CD. When the amount of β-CD was 0.4574 g, the morphology of product was tremella-like BiOBr with a highest photocatalytic activity under visible light irradiation. |
