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.
