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0.4574g时,所制得的BiOBr为银耳状,且其光催化性能最好。A solvothermal method to prepare tremell-like BiOBr was developed by using β-CD, Bi（NO3 ）3 · 5 H2O and KBr as starting materials. The nano BiOBr was characterized by Xray 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.
