Description
Summary:[Display omitted] •Floatable foam-supported BiOBr composite photocatalysts were synthesized.•The loading amount of BiOBr was adjustable.•BiOBr composites exhibited the commendable photocatalytic activity.•Mechanisms for the photocatalytic performance were discussed. A series of graphitic carbon nitride foam-supported BiOBr composites (CNB) were prepared by a simple two-step method, and they were characterized by XRD, SEM, FT-IR, UV–vis DRS and PL. The photocatalytic activity was evaluated by the degradation of rhodamine B (RhB) under visible light irradiation. The results revealed that CNB samples not only possessed commendable photocatalytic activity but also could float beneath the liquid surface. In view of its outstanding activity and recyclability, CNB photocatalysts exhibit promising potential application in environment treatment.
