摘要：

A ternary BiOBr/CS/g-C3N4 composite was synthesized by the in-situ attachment of carbon spheres (CS) to the surface of g-C3N4, and BiOBr nanosheets by a solvothermal route. The properties of the composite were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), photoluminescence (PL) and diffuse reflectance spectroscopy (DRS) techniques. The photocatalytic activity of the composite was analyzed through the photocatalytic degradation of rhodamine (RhB) dye under the visible-light irradiation. The successful photocatalytic execution of BiOBr/CS/g g-C3N4 composite lost fewer activity after five consecutive cycles, demonstrating the excellent stability of the material.
