A　visible-light-driven　plasmonic　Ag/AgBr/ZnFe2O4　nanocomposite　has　been　successfully　synthesized　via　a　deposition-precipitation　and　photoreduction　through　a　novel　one-pot　process.　X-ray　diffraction　spectroscopy,　X-ray　photoelectron　spectroscopy,　scanning　electron　microscopy,　transmission　electron　microscopy　and　UV-vis　diffuse　reflectance　spectroscopy　were　employed　to　investigate　the　crystal　structure,　chemical　composition,　morphology,　and　optical　properties　of　the　as-prepared　nanocomposites.　The　photocatalytic　activities　of　the　nanocomposites　were　evaluated　by　photodegradation　of　Rhodamine　B　(RhB)　and　phenol　under　visible　light.　The　results　demonstrated　that　the　obtained　Ag/AgBr/ZnFe2O4　nanocomposites　exhibited　higher　photocatalytic　activity　as　compared　to　pure　ZnFe2O4.　In　addition,　the　sample　photoreduced　for　20　min　and　calcined　at　500　°C　achieved　the　highest　photocatalytic　activity.　Furthermore,　the　Ag/AgBr/ZnFe2O4　nanocomposite　has　high　stability　under　visible　light　irradiation　and　could　be　conveniently　separated　by　using　an　external　magnetic　field.　©　2014　Elsevier　Ltd.
