A　novel　visible-light　photocatalyst,　Sb2S3,　Was　synthesized　with　a　simple　method.　The　specimen　was　characterized　by　X-ray　diffraction,　transmission　electron　microscopy,　Brunauer-Emmett-Teller　(BET)　surface　area　analysis,　and　UV-vis　diffuse　reflectance　spectroscopy.　The　results　revealed　that　the　as-synthesized　sample　was　orthorhombic　phase　and　consisted　of　rodlike　particles.　It　possessed　a　surface　area　of　15.1　m(2).g(-1),　and　the　band　gap　was　about　1.66　eV.　The　photocatalytic　activity　of　Sb2S3　nanorods　was　evaluated　by　the　decomposition　of　methyl　orange　in　aqueous　solution　under　visible-light　irradiation.　The　results　demonstrated　that　the　photodegradation　ratio　of　methyl　orange　was　up　to　97%　after　30　min　of　irradiation,　which　was　much　better　than　that　of　CdS　and　TiO2-xNx　under　the　same　condition.　Meanwhile,　the　possible　mechanism　of　the　photocatalytic　reaction　had　also　been　studied　by　liquid　chromatography-mass　spectrometry,　and　the　center　dot　OH　had　been　detected　also　by　terephthalic　acid　photoluminescence　probing　technique.
