A magnetic Fe 3 O 4 /BiOBr microsphere has been prepared by a simple and effective method. The Fe 3 O 4 /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 Fe 3 O 4 /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.
