Abstract：

An　excellent　visible-light-responsive　(from　400　to　550　nm)　TiO2-xNx　photocatalyst　was　prepared　by　a　simple　wet　method.　Hydrazine　was　used　as　a　new　nitrogen　resource　in　this　paper.　Self-made　amorphous　titanium　dioxide　precursor　powders　were　dipped　into　hydrazine　hydrate,　and　calcined　at　low　temperature　(110　°C)　in　the　air.　The　TiO2-xNx　was　successfully　synthesized,　following　by　spontaneous　combustion.　The　photocatalyst　was　characterized　by　X-ray　diffraction　(XRD),　Brunauer-Emmett-Teller　(BET),　transmission　electron　microscope　(TEM),　UV-Vis　diffuse　reflectance　spectrometer　(DRS),　and　X-ray　photoelectron　spectroscopy　(XPS).　Analysis　of　XPS　indicated　that　N　atoms　were　incorporated　into　the　lattice　of　the　titania　crystal　during　the　combustion　of　hydrazine　on　the　surface　of　TiO2.　Ethylene　was　selected　as　a　target　pollutant　under　visible-light　excitation　to　evaluate　the　activity　of　this　photocatalyst.　The　newly　prepared　TiO2-xNx　photocatalyst　with　strong　photocatalytic　activity　and　high　photochemical　stability　under　visible-light　irradiation　was　firstly　demonstrated　in　the　experiment.　©　2007　Elsevier　Inc.　All　rights　reserved.
