Abstract: To obtain multifunctional bismuth series photocatalytic materials with strong photocatalytic activity,superior magnetic stability and effective magnetic separation, Bismuth bromide oxide (BiOBr) was organically modified by sodium dodecylbenzene sulfonate (SDBS) and carried by magnetic bentonite (MB). Flower-like spherical SDBS modified MB-based supported BiOBr (SDBS/BiOBr-MB)composite photocatalyst was successfully synthesized by synthesizing some methods of load modification, semiconductors coupling and morphology control. Subsequently, the synthesized samples were characterized by a series of characterization technologies and the photocatalytic performance was investigated by Rhodamine B (RhB) under visible light irradiation. The experimental results confirmed the flower-like spherical SDBS/BiOBr-MB boosted absorption and utilization of visible light. While the effective separation of photogenerated carriers can be achieved due to Fe3O4@BiOBr heterojunction. In addition, the introduction of MB effectively reduced agglomeration of BiOBr and achieved efficiently solid-liquid separation by an external magnet. After five recycles, the SDBS/BiOBr-MB photocatalyst still exhibited high photocatalytic activity and stability for RhB (92%) under visible-light irradiation. Therefore, this study can provide valuable reference for the integrated modification of BiOBr and other visible-light photocatalysts.
