HYDROTHERMAL SYNTHESIS OF TIO2/BIOBR COMPOSITES WITH ENHANCED PHOTOCATALYTIC ACTIVITY

ABSTRACT
The hydrothermal method is used to fabricate the TiO2/BiOBr composite. The X-ray diffraction, SEM, X-ray photoelectron spectroscopy, and ultraviolet-visible diffuse reflectance spectroscopy are employed to characterize its crystal structure, physical morphology, chemical composition, and light absorption. Its photocatalytic performance and stability are analyzed by the photocatalytic degradation rate of rhodamine B solution under sunlight irradiation. The composite exhibits the optimal photocatalytic effect when the Ti:Bi molar ratio is 4:1.
