摘　　要：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.
