Abstract：

Visible-light-driven　photocatalysts,　CdS/TiO2　nanocomposites　were　synthesized　by　a　simple　hydrothermal　method.　Their　formation　and　structures　were　characterized　by　X-ray　diffractometer,　transmission　electron　microscopy,　diffuse　reflectance　spectroscopy,　and　X-ray　photoelectron　spectroscopy.　Taking　rhodamine　B　(RhB)　as　a　model,　their　photocatalytic　activities　in　aqueous　phase　under　visible　light　irradiation　(420　<　λ　<　800　nm)　were　tested.　The　results　showed　that　the　composite　of　CdS　and　TiO2　with　appropriate　oxidation　reduction　energy　levels　enhanced　the　charge　separation　and　extended　the　absorption　response　into　visible　light　region.　Thus,　the　photosensitized　degradation　of　RhB　was　largely　enhanced.　The　degradation　mechanism　was　explored　concretely.　©　2013　Elsevier　Ltd.　All　rights　reserved.
