ZnBi2O4/rGO hybrid, Indigo Carmine, visible-light photodegradationAbstract
A novel ZnBi2O4/rGO hybrid catalysts had been synthesized by a simple precipitation method. The crystallinity, structural, and morphological features were studied by XRD, FE-SEM and UV-Vis diffused reflectance techniques. The photocatalytic activity of ZnBi2O4/rGO catalysts were evaluated by degradation of Indigo Carmine dye under visible-light irradiation. The enhancement of photocatalytic properties of ZnBi2O4/rGO attributed to the synergistic effect between ZnBi2O4 and rGO, which effectively separation of the photogenerated electron-hole pairs in ZnBi2O4. Moreover, the obtained ZnBi2O4/rGO displayed high chemical stability after four consecutive experiments under visible light.Downloads
