| Abstract: | In this study, ternary ZnO/BiOBr/C-Dots photocatalysts were successfully prepared by a simple strategy. Then, their characteristics such as structure, morphology, chemical, optical, textural, and photocatalytic performances were fully investigated. This study demonstrated that the ZnO/BiOBr/C-Dots nanocomposites showed remarkably increased photocatalytic performances compared with the ZnO and ZnO/BiOBr samples. In decolorization of RhB upon visible light, the highest activity was obtained when the volume of C-Dots was 0.25?mL, which was about 39.7 and 2.7?times premier than the ZnO and ZnO/BiOBr photocatalysts, respectively. In the ternary nanocomposites, the increased performance was mainly ascribed to the formed heterojunction between the counterparts, up conversion characteristics of C-Dots, and visible-light harvesting ability of BiOBr. The reactive species trapping experiments proved that  | |
