In situ synthesis of BiOCl/Bi4O5Br2 composite and investigation of the photocatalytic performance for tetracycline degradation
In this paper,BiOCl/Bi4O5Br2 composites were prepared by in situ reduction and oxidation of BiOCl for tetracycline wastewater pollution,and the photocatalytic performance of the materials was explored by photocatalytic degradation of tetracycline(TC).The photocatalytic experimental results showed that the removal efficiency of BiOCl/Bi4O5Br2 for TC reached 64%,which was close to 2.5 times that of the original BiOCl.After that,we explored the possible reasons for the enhanced photocatalytic performance by XRD,UV-vis diffuse reflectance absorption spectroscopy and EIS characterization.The results show that the constructed BiOCl/Bi4O5Br2 composites have high separation efficiency of carriers and strong light absorption in the visible region,and the photocatalytic performance is thus enhanced.
