Abstract：

Visible　light-response　bismuth　bromide　oxide　(BiOBr)　is　a　widely　sought-after　semiconductor　nanomaterial　due　to　its　high　photocatalytic　activity,　but　its　applications　have　been　limited　by　complex　synthesis　methods　and　low　cyclability.　Hence,　we　successfully　deposited　BiOBr　nanosheets　on　carbon　fiber　cloth　(CFC)　by　chemical　bath　precipitation　method　to　obtain　efficient　and　easily　recyclable　CFC/BiOBr-x　photocatalysts　(4　×　4　cm2).　After　in-situ　growth　of　BiOBr　nanosheets　on　CFC,　the　diameter　of　a　single　fiber　(CFC/BiOBr-6)　was　increased　from　6.9　to　7.4　μm.　Under　visible　light　irradiation,　CFC/BiOBr-6　exhibits　excellent　photocatalytic　activity　toward　RhB　(completely　degrade)　and　LVFX　(88.9　%)　within　120　min,　respectively.　In　addition,　CFC/BiOBr-6　still　maintained　good　photocatalytic　activity　after　four　cycles　(97.9　%).　Therefore,　CFC/BiOBr-6　possesses　great　potential　for　practical　photocatalytic　applications.　©　2023　Elsevier　B.V.
