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.
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.
