Abstract

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)₃5H₂O 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.
