Porous　S-doped　bismuth　vanadate　with　an　olive-like　morphology　and　its　supported　cobalt　oxide　(y　wt%　CoOx/BiVO4-delta　S0.08,　,　y　=　0.1,　0.8,　and　1.6)　photocatalysts　were　fabricated　using　the　dodecylamine-assisted　alcohol-hydrothermal　and　incipient　wetness　impregnation　methods,　respectively.　It　is　shown　that　the　y　wt%　CoOx/BiVO(4-delta)S0.08　photocatalysts　were　single-phase　with　a　monoclinic　scheetlite　structure,　a　porous　olive-like　morphology,　a　surface　area　of　8.8-9.2　m(2)/g,　and　a　bandgap　energy　of　2.38-2.41　eV.　There　was　the　co-presence　of　surface　Bi5+,　Bi3+,　V5+,　V3+,　Co3+,　and　Co2+　species　in　y　wt%　CoOx/BiVO4-delta　delta　S-0.08.　The　0.8　wt%　CoOx/BiVO4-delta　S0.08　sample　performed　the　best　for　methylene　blue　degradation　under　visible-light　illumination.　The　photocatalytic　mechanism　was　also　discussed.　We　believe　that　the　sulfur　and　CoOx　codoping,　higher　oxygen　adspecies　concentration,　and　lower　bandgap　energy　were　responsible　for　the　excellent　visible-light-driven　catalytic　activity　of　0.8　wt%　CoOx/BiVO(4-delta)S0.08.　(C)　2013　Elsevier　Masson　SAS.　All　rights　reserved.
