Construction of a hydrangea-like Bi2WO6/BiOCl composite as a high-performance photocatalyst

Bi 2 WO 6 flower-like microspheres were acted as porous templates for depositing BiOCl to prepare a hydrangea-like Bi 2 WO 6 /BiOCl composite. The Bi 2 WO 6 /BiOCl heterojunction exhibits a high photocatalytic activity under visible light.
