Facile and fast synthesis of urchin-shaped Fe3O4@Bi2S3 core-shell hierarchical structures and their magnetically recyclable photocatalytic activity

Abstract

In this work, we have developed a facile and rapid synthesis of urchin-shaped Fe3O4@Bi2S3 core-shell hierarchical structures through a sonochemical method. The as-prepared Fe3O4@Bi2S3 hierarchical core-shell structures show excellent photocatalytic efficiency for the degradation of rhodamine B (RhB) and retained this photocatalytic activity after being recycled five times with the help of an external magnetic field. The possible mechanism for the formation of the urchin-shaped Fe3O4@Bi2S3 core-shell structures is also proposed. These novel urchin-shaped Fe3O4@Bi2S3 core-shell structures may have potential applications in water treatment, sensors, and energy storage.
