BiOBr　synthesized　by　alcoholysis　precipitation　is　used　in　the　preparation　of　BiPO4/BiOBr　composites　by　adding　H3PO4.　Pristine　BiOBr　and　a　series　of　BiPO4/BiOBr　composites　have　been　successfully　synthesized　using　an　entirely　room-temperature　production　process.　X-ray　powder　diffraction,　scanning　electron　microscopy,　High-resolution　transmission　electron　microscopy,　X-ray　photoelectron　spectroscopy,　UV–vis　absorption　spectroscopy　were　used　to　investigated　the　bulk　structure,　surface　morphology,　element　composition　and　optical　properties　of　the　samples.　The　degradation　effect　of　different　proportions　of　BiPO4/BiOBr　composites,　BiOBr　and　BiPO4　on　Rhodamine　B　(RhB)　was　evaluated　under　visible　LED　light　irradiation.　Compared　to　pure　BiOBr　and　BiPO4,　the　as-synthesized　BiPO4/BiOBr　composites　showed　enhanced　performance,　with　30%　BiPO4/BiOBr　composite　showing　the　best　performance,　as　it　could　degrade　95.66%　of　RhB　(100　ml,　15　mg/L)　within　120　min.　The　enhanced　photocatalytic　activity　of　BiPO4/BiOBr　was　attributed　to　the　heterojunction　formation　between　BiOBr　and　BiPO4　and　efficient　charge　separation.　©　2019　The　Chemical　Society　Located　in　Taipei　&　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
