A magnetic Fe3O4/BiOBr microsphere has been prepared by a simple and effective method. The Fe3O4/BiOBr magnetic photocatalyst exhibited excellent photocatalytic activity for the degradation of Rhodamine B (RhB) under visible-light irradiation. RhB in aqueous solution was fully photodegraded after 100 min. The Fe3O4/BiOBr photocatalyst was easily recovered after liquid-phase photodegradation reaction because of its property, which could facilitate the practical running of an industrial wastewater treatment.
