摘　　要：通过二次水热法制备了Cu-BTC/BiOBr(Cu-BTC/BOB)复合光催化剂。分别利用SEM、XRD、DRS、电化学等表征方法对所制备的光催化剂进行形貌、晶体结构、光学特性、电化学特性研究。通过在模拟可见光下对罗丹明B(RhB)进行降解考察Cu-BTC/BOB复合材料的光催化活性。实验结果表明,Cu-BTC/BOB复合材料的降解效果均明显优于Cu-BTC和BiOBr,Cu-BTC与BiOBr质量比为25∶100的复合材料光催化性能最佳,在60 min内对RhB的降解效率可达96.3%,经过3次循环后仍有一定的光催化活性。Cu-BTC/BiOBr(Cu-BTC/BOB)composite photocatalysts were prepared by a two-step hydrothermal method.The morphology,crystal structure,optical properties and electrochemical properties of the prepared photocatalysts were studied by SEM,XRD,DRS and electrochemical methods.The photocatalytic activity of Cu-BTC/BOB composites was investigated by the degradation of rhodamine B(RhB)under simulated visible-light irradiation.The experimental results showed that the degradation performance of Cu-BTC/BOB composites was significantly better than that of Cu-BTC and BiOBr,respectively.When the mass ratio of Cu-BTC to BiOBr is 25∶100,the composite exhibits the best photocatalytic performance.The degradation efficiency of RhB reached 96.3%within 60 min.The composite still possessed photocatalytic activity after 3 cycling tests.
