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.
