Abstract：

The　C-doped　CdO　photocatalysts　were　simply　prepared　by　high-temperature　solid-state　process.　The　as-prepared　photocatalysts　were　characterized　by　X-ray　powder　diffraction　(XRD),　diffuse　reflectance　spectroscopy　(UV-Vis　DRS),　scanning　electron　microscopy　(SEM)　and　X-ray　photoelectron　spectroscopy　(XPS).　The　results　demonstrated　that　the　carbon　was　doped　into　CdO,　resulting　in　the　red-shift　of　the　optical　absorption　of　CdO.　The　photocatalytic　behavior　of　CdO　and　C-doped　CdO　was　evaluated　under　the　visible　light　irradiation　by　using　the　photocatalytic　hydrogen　evolution　as　a　model　reaction.　The　C-doped　CdO　photocatalysts　had　higher　photocatalytic　activity　over　parent　CdO　under　visible　light　irradiation.　The　results　indicated　that　the　H2　production　was　due　to　the　existence　of　CdS　and　the　enhancement　of　visible　light　photocatalytic　activity　of　H2　production　was　originated　from　the　doping　of　carbon　into　the　CdO　lattice.　The　probably　reaction　mechanism　was　also　discussed　and　proposed.　Copyright　©　2012　Quan　Gu　et　al.
