A　visible-light　catalytic　composite　material　of　regenerated　cellulose　supported　SnS2　(SnS2/regenerated　cellulose)　was　synthesized　via　microwave-assisted　heating　method　at　120℃　with　SnCl4　and　thioacetamide　as　the　source　of　Sn　and　S　respectively.　The　obtained　SnS2/regenerated　cellulose　was　characterized　by　power　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　transmission　electron　microscopy　(TEM),　UV-vis　diffuse　reflectance　spectra　(DRS)　and　specific　surface　areas　(BET).　The　results　show　that　the　prepared　SnS2　is　a　phase　with　hexagonal　crystal　structure　and　the　composite　exhibited　a　nano-sized　lamellar　structure　with　0.52　nm　of　interlayer　spacing.　In　comparison　with　the　simple　SnS2,　the　composite　SnS2/regenerated　cellulose　has　larger　absorption　band　for　visible　light　and　specific　surface　area.　Furthermore,　the　microwave　heating　method　can　greatly　reduce　the　synthesis　temperature　and　the　reaction　time.　The　composite　prepared　at　120℃　for　20~80　min　exhibited　excellent　photocatalytic　performance.　The　removal　efficiency　for　Rhodamine　B　(20　mg/L)　can　reach　100%　within　3　h　by　the　composite　under　visible　light　irradiation,　and　the　degradation　ratio　of　RhB　can　still　reach　88%　by　the　composite　even　after　five　cycles　of　use/regeneration.　©　All　right　reserved.
