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
