以硝酸铋、溴化钠和 CNTs 为原料，采用醇热法制备 BiOBr/ CNTs 复合管光催化剂。采用场发射扫描电子显微镜（FESEM）对光催化剂的形貌进行了表征；以罗丹明废水溶液的降解为目标反应，考察了催化剂在可见光下的催化活性。结果表明，三维花球状 BiOBr 在可见光下有良好的光降解性能，加入 CNTs 后进一步提高了对光的吸收和利用，因此所制备的 BiOBr/ CNTs 复合光催化剂表现出较高的光催化活性。

BiOBr and carbon nanotubes(CNTs)composite photocatalysts were prepared by hydrothermal method using bismuth nitrate pentahydrate,sodium bromide and CNTs as a source. The samples were characterized by FESEM. The photodegradation of Rhodamin B solution was used to evaluate the photocat-alytic activity of the catalyst under visible-light irradiation. The results suggest that the BiOBr/ CNTs keep 3D microspherical BiOBr architectures. The prepared BiOBr/ CNTs photocatalyst shows higher light photo-catalytic activity because the black CNTs increase the absorption and utilization of light.
