Z-type heterojunction degradation of tetracycline by 2D g-CN with 3D oxygen vacancy BiWO.

Photocatalytic degradation is a promising strategy for environmental remediation. Graphitic carbon nitride (g-CN) is the most extensively reported metal-free material. Hierarchical flower-shaped BiWO particles were obtained using a simple hydrothermal method, with petals of flower-like BiWO with oxygen vacancies (BiWO OVs) with controlled content successfully decorated on g-CN nanosheets.
