Synthesis and visible light photocatalytic performance of HC/BiOBr/ Bi12TiO20 microspheres

HC/BiOBr/Bi12TiO20 microspheres with good photocatalytic activity were prepared by solvothermal method. The composition and morphology of HC/BiOBr/Bi12TiO20 & nbsp;were characterized by XRD, EDS, HRTEM and SEM. After irradiation with 7 W LED lamp for 160 min, the degradation efficiency of composite for rhodamine B, methyl blue, methyl orange was 98.55%, 30.74% and 16.67%, respectively. The degradation efficiency of 70 W metal halide lamps and natural light was better than that of LED lamps. HC/BiOBr/Bi12TiO20 has good reusability, strong photocatalytic activity and degree of mineralization, which is mainly attributed to its large specific surface area and high separation ability of photoinduced carriers.

Automated summary

HC/BiOBr/Bi12TiO20 microspheres prepared by solvothermal method showed good photocatalytic activity and reusability, which can be attributed to their large specific surface area and high separation ability of photoinduced carriers.
