Porous　nanosheet-aggregated　persimmon-like　bismuth　oxybromide　(BiOBr)　were　successfully　prepared　for　the　first　time　using　polyvinyl　pyrrolidone　(PVP)-assistctd　solvothermal　strategy　with　bismuth　nitrate　and　cetyltrimethyl　ammonium　bromide　(CTAB)　as　Bi　and　Br　sources.　Physicochemical　properties　of　the　hierarchical　microstructure　BiOBr　materials　were　characterized　by　means　of　numerous　analytical　techniques,　and　their　pholocatalytic　activities　were　evaluated　for　the　removal　of　methylene　blue　(MB)　under　visible-light　illumination.　It　is　found　that　the　solvothermal　time　and　PVP　addition　had　a　significant　influence　on　the　particle　morphology　and　crystallinity　of　the　product.　The　porous　sheet-aggregated　persimmon-like　BiOBr　sample　could　be　obtained　after　solvothermal　treatment　at　120　degrees　C,　for　12　h　in　the　presence　of　0.7　g　PVP.　The　porous　persimmon-like　BiOBr　sample　with　a　surface　area　of　4　m(2).g(-1)　and　a　bandgap　energy　of　2.64　eV　possessed　good　optical　absorption　property　in　visible-light　regions　and　showed　excellent　visible-light-driven　photocatalytic　activity　and　stability　for　MB　degradation.　It　is　concluded　that　the　high　visible-light-driven　catalytic　performance　of　the　porous　sheet-aggregated　persimmon-like　BiOBr　sample　is　associated　with　its　high　surface　area,　porous　structure,　and　low　bandgap　energy　as　well　as　the　unique　particle　morphology.
