Fe3O4-ZnWO4 hybrid microspheres: facile synthesis and magnetically recyclable photocatalytic performance

Fe₃O₄-ZnWO₄ composite microspheres with magnetically recyclable photocatalytic performance have been firstly synthesised by a simple refluxing method under mild conditions. The as-prepared Fe₃O₄-ZnWO₄ composites show good photocatalytic efficiency in degradation of rhodamine B under UV light irradiation and can be recycled five times by magnetic separation without major loss of activity, the magnetic property of Fe₃O₄-ZnWO₄ sample has been studied also. Microspheres show potential use on dye degradation from the solution considering their magnetic recovery properties.
