Abstract：

This　work　provides　a　simple　approach　of　the　F　−　-assisted　one-pot　hydrothermal　reaction　to　successfully　synthesize　Bi　2　WO　6　hierarchical　erythrocyte　microspheres.　The　importance　role　of　F　−　was　systematically　investigated　by　comparing　different　type　of　halogen　ions,　hydrothermal　temperature　and　time.　The　possible　growth　mechanism　of　Bi　2　WO　6　hierarchical　structures　was　proposed.　The　hierarchical　erythrocytes　were　formed　through　the　well-ordered　and　oriented　self-assembly　of　thin　Bi　2　WO　6　nanoplate　primary　subunits.　F　−　ions　were　absorbed　on　Bi　2　WO　6　nanoplate　surface　to　suppress　the　nanoplate　stack　but　to　induce　a　self-assembly　through　the　edge　interaction　of　Bi　2　WO　6　nanoplates　into　erythrocyte-like　hierarchical　microspheres　superstructures.　This　erythrocyte　structure　narrowed　the　band　gap　energy　and　enhanced　the　visible-light　photocatalytic　activity　of　Bi　2　WO　6　.　Moreover,　superoxide　radical　anions　and　h　+　were　revealed　as　the　main　active　species　responding　for　the　RhB　degradation　on　Bi　2　WO　6　under　visible　light　irradiation.　©　2017　Elsevier　B.V.
