Abstract
In this work, the influence of graphite-like C3N4 (g-C3N4) loading on the photocatalytic performance of Bi12O17Br2/Bi2O3 composite was studied. The results indicated that g-C3N4-Bi12O17Br2/Bi2O3 photocatalysts displayed much higher photocatalytic efficiency for the phenol red degradation than the bare Bi2O3 and Bi2O3/Bi12O17Br2 composite under visible light illumination. The best photocatalytic performance of the composite sample with almost 100% phenol red degradation located at g-C3N4-Bi12O17Br2/Bi2O3-50 under visible light illumination for 80 mins. This excellent photocatalytic performance was displayed according to the efficient separation and transportation of the photogenerated charges, which was resulted from the coupling of C3N4 and Bi12O17Br2/Bi2O3.
