采用离子交换法制备了一种新型复合光催化剂AgCl/Bi3O4Cl。用各种方法对合成的复合材料进行了表征，并在可见光照射下研究了其降解RhB的光催化活性。结果表明，在Bi3O4Cl中引入AgCl，提高了Bi3O4Cl的比表面积、光吸收性能和电子空穴对的分离效率，使复合材料具有较高的光催化活性。最佳AgCl/Bi3O4Cl样品对RhB的降解率为0.048 min−1，分别是AgCl和Bi3O4Cl的2.2倍和2.4倍。
This work presents a novel composite photocatalyst, AgCl/Bi3O4Cl, which was prepared using an ion-exchange method. The synthesized composite was characterized by various techniques and its photocatalytic activity was investigated in RhB degradation under visible light irradiation. Results indicated that the introduction of AgCl into Bi3O4Cl promoted the specific surface area, light absorption performance and the separation efficiency of electron–hole pairs, which resulted in a high photocatalytic activity of the composite. The optimal AgCl/Bi3O4Cl sample showed a RhB degradation rate of 0.048 min− 1, which was 2.2 and 2.4 times higher than those of AgCl and Bi3O4Cl, respectively.
