Mesoporous　TiO(2-x)A(y)　(A　=　N,　S)　thin　films　were　fabricated　using　thiourea　as　a　doping　resource　by　a　combination　of　sol-gel　and　evaporation-induced　self-assembly　(EISA)　processes.　The　results　showed　that　thiourea　could　serve　two　functions　of　co-doping　nitrogen　and　sulfur　and　changing　the　mesoporous　structure　of　TiO2　thin　films.　The　resultant　mesoporous　TiO(2-x)A(y)　(A　=　N,　S)　exhibited　anatase　framework　with　a　high　porosity　and　a　narrow　pore　distribution.　The　formation　of　the　O-Ti-N　and　O-Ti-S　bonds　in　the　mesoporous　TiO(2-x)A(y)　(A　=　N,　S)　were　substantiated　by　the　XPS　spectra.　A　new　bandgap　in　visible　light　region　(520　nm)　corresponding　to　2.38　eV　could　be　formed　by　the　co-doping.　After　being　illuminated　for　3　h,　methyl　orange　could　be　degraded　nearly　completely　by　the　co-doped　sample　under　both　ultraviolet　irradiation　and　visible　light　illumination.　While　pure　mesoporous　TiO2　could　only　degrade　60%　methyl　orange　under　UV　illumination　and　showed　negligible　photodegradation　capability　in　the　visible　light　range.　Furthermore,　the　photo-induced　hydrophilic　activity　of　TiO2　film　was　improved　by　the　co-doping.　The　mesoporous　microstructure　and　high　visible　light　absorption　could　be　attributed　to　their　good　photocatalytic　acitivity　and　hydrophilicity.　(C)　2009　Elsevier　Masson　SAS.　All　rights　reserved.
