چکیده
In this work, a magnetically separable montmorillonite/Fe3O4 sphere composite (MMT/Fe) was synthesized by simple polyol thermal method. The characteristics of the as-preparation composites were checked XRD, SEM, PL technologies. addition, photocatalytic activities products degradation Rhodamin B (RhB) under visible light. results showed that MMT/Fe exhibited high activity for RhB removal light irradiation. improved can be ascribed to low combination rate photoinduced electron/hole pairs. Especially, recovered easily using an external magnetic field and posse stability after six runs. These properties as prepared could promising photocatalyst organic dye contaminants.
