Nitrogen　and　sulfur　co-doped　mesoporous　TiO2　thin　films　were　fabricated　using　thiourea　as　a　doping　resource　by　the　combination　of　the　sol-gel　and　evaporation-induced　self-assembly　(EISA)　processes.　Scanning　electron　microscopy　(SEM),　X-ray　diffraction　(XRD),　X-ray　photoelectron　spectroscopy　(XPS),　N-2　adsorption-desorption,　and　UV-vis　spectra　were　performed　to　characterize　the　as-synthesized　mesoporous　TiO2　materials.　The　XPS　result　shows　that　O-Ti-N　and　O-Ti-S　bonds　in　the　(S,　N)-codoped　mesoporous　TiO2　were　formed.　The　resultant　mesoporous　(S,　N)-codoped　TiO2　exhibited　anatase　framework　with　a　high　porosity　and　a　narrow　pore　distribution.　After　being　illuminated　for　3　h,　methyl　orange　(MO)　could　be　degraded　completely　by　the　co-doped　sample　under　the　ultraviolet　irradiation,　whereas　mesoporous　TiO2　film　without　doping　could　only　degrade　60%　MO.　After　being　illuminated　by　visible　light,　the　water　contact　angles　of　the　mesoporous　co-doped　TiO2　samples　decreased　slightly,　but　the　pure　TiO2　mesoporous　film　exhibited　no　change　in　the　hydrophilicity.
