Abstract：

Magnetic　Bi2WO6-NiFe2O4　visible-light　photocatalyst　was　successfully　synthesized　by　a　simple　hydrothermal　method.　The　as-prepared　photocatalysts　were　characterized　by　X-ray　diffraction　(XRD),　UV-Visible　diffuse　reflectance　spectra　(UV-Vis　DRS),　scanning　electron　microscopy　(SEM)　and　magnetic　property　measurement　system(MPMS).　The　photocatalytic　activities　of　the　photocatalyst　were　evaluated　by　degradation　of　Rhodamine　B　(RhB)　in　aqueous　solution　under　visible　light　at　different　pH　value.　The　results　demonstrated　that　the　highest　RhB　degradation　rate　(＞98%)　was　achieved　by　Bi2WO6-NiFe2O4　photocatalyst　when　the　pH　was　5.　Bi2WO6-NiFe2O4　photocatalyst　can　be　easily　separated　from　solution　using　an　external　magnetic　field.　©,　2015,　Journal　of　Functional　Materials.　All　right　reserved.
