Abstract：

We　developed　a　simple　X　−　-assisted　(X　=　Cl,　Br,　I)　one-pot　hydrothermal　reaction　to　successfully　synthesize　a　series　of　BiOX/Bi　2　WO　6　heterojunction.　The　effect　of　different　halogens　and　their　addition　amount　on　the　photocatalytic　performance　of　BiOX/Bi　2　WO　6　composites　was　investigated　using　benzyl　alcohol　selective　oxidation　under　visible-light　irradiation.　All　BiOX　could　enhance　the　photocatalytic　activity　of　Bi　2　WO　6　,　but　the　BiOBr　was　the　optimum　for　the　maximum　improvement　of　Bi　2　WO　6　.　The　match　of　energy　band　structure　between　BiOX　and　Bi　2　WO　6　resulted　in　the　highly　efficient　separation　of　photogenerated　charges,　which　was　mainly　attributed　to　their　fundamental　distinction　of　the　photocatalytic　activity.　This　work　clarified　the　essential　distinction　in　photocatalytic　performance　of　the　different　halogen　of　BiOX/Bi　2　WO　6　heterojunction,　and　also　provided　guidance　for　the　construction　of　efficient　heterojunction　photocatalysts.　©　2018　Elsevier　B.V.
