description | Heterojunction engineering has shown great potential in the field of photocatalysis to deal with environmental pollutants. The design and synthesis of heterojunction photocatalysts with high efficiency and stability still face great challenges. In this work, a novel CdS quantum dots (QDs) decorated 3D Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> hierarchical nanoflower heterojunction photocatalyst (Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub>/CdS QDs) was synthesized to investigate the photocatalytic Rhodamine B (RhB) degradation performance. CdS QDs were evenly distributed on the surface of the Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> nanoflower. Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub>/CdS QDs showed significantly enhanced photocatalytic RhB degradation performance compared with pristine Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> and CdS QDs. The enhanced photocatalytic performance was attributed to the synergistic effect of hierarchical structure and heterojunction, which greatly increased the active sites of the reaction and the photogenerated carriers transfer. |
