Three-dimensionally (3-D) hierarchical BiOBr microspheres have been successfully synthesized using a facile and efficient solvothermal method in the reaction system consisting of Bi(NO3)(3)center dot 5H(2)O and KBr as well as ethylene glycol (EG). The characterized results showed that all BiOBr microspheres consisted of pure tetragonal BiOBr phase with good crystallinity. The photocatalytic property of 3-D BiOBr microspheres was investigated by the photodegradation of Rhodamine B (RhB) under visible light irradiation, the reaction results revealed that the as-prepared microspheres exhibited excellent visible-light-induced photocatalytic activity. Recycling test experiments indicated that the BiOBr microspheres had higher stability and recyclability.
