Hierarchical g-C3N4/BiOBr for Enhancing Photocatalytic Performance Under visible light

Hierarchical g-C 3 N 4 /BiOBr composite photocatalysts were successfully synthesized via a facile one-pot solvothermal method. Characteristics of the as-prepared photocatalysts were determined by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV–visible diffuse reflectance spectroscopy (UV-vis DRS). Removing performance of Rhodamine B (RhB) and tetracycline (TC) were also studied by the as-prepared photocatalysts under LED blue light irradiation. Results indicated that flower-like BiOBr hierarchical microspheres were successfully fabricated and interwoven by the flake-like g-C 3 N 4 , the photocatalysts showed highest photodegradation RhB and TC when the g-C 3 N 4 attained 0.8% under LED blue light irradiati o n.
