Abstract

Abstract : This work has developed a facile strategy to create magnetically separable, core‐shell structured composites consisting of a magnetic Ag nanowires (NWs)/Fe3 O4 cores and an outer mesoporous TiO2 (mTiO2 ) shell using a sol–gel process and subsequent hydrothermal treatment. Benefiting from the mesoporous anatase TiO2 as well as the unique structures of the composite, the resulting Ag NWs/Fe3 O4 @mTiO2 composite was employed as a catalyst for removal of the organic contaminants through a colorimetric photocatalytic degradation assay using methylene blue (MB) as a model contaminant. Moreover, the photocatalysts can be easily separated and recycled with an external magnetic field and possess prominent recoverability.
