Hydrothermal fabrication of N-doped (BiO)2CO3: Structural and morphological influence on the visible light photocatalytic activity

- Persimmon-like, flower-like N-doped (BiO)2CO3 superstructures were prepared.
- The superstructures were fabricated by one-step hydrothermal method.
- The hydrothermal temperature controlled the morphological structure.
- N-doped (BiO)2CO3 superstructure showed enhanced photocatalytic activity.
- The high activity can be ascribed to doped nitrogen and hierarchical structure.
