Abstract：

The　photocatalytic　overall　conversion　of　CO2　with　H2O　to　chemical　fuel　and　oxygen　mimicking　natural　photosynthesis　is　a　huge　challenge　in　photocatalysis.　This　work　shows　the　achievement　of　the　solar-driven　photocatalytic　overall　CO2　reduction　with　H2O　to　CO　and　O2　over　a　Persian　buttercup-like　BiOBrxCl1-x　solid　solution.　A　CO　generation　rate　of　15.86　μmol　g−1　h−1　with　the　approximate　stoichiometric　O2　evolution　is　yielded　on　BiOBr0.6Cl0.4　solid　solution　under　simulated　solar　light　irradiation,　which　was　about　7.5　and　10.2　times　higher　than　that　of　pure　BiOCl　(2.11　μmol　g−1　h−1)　and　BiOBr　(1.55　μmol　g−1　h−1),　respectively.　The　enhanced　photoactivity　is　contributed　to　the　mediate　band　gap　and　energy　level　tuned　by　the　formation　of　BiOBrxCl1-x　solid　solution　to　facilitate　the　separation　of　photogenerated　charges.　Besides　the　unique　electron　structure,　the　photoinduced　oxygen　vacancy　(OV)　formed　on　BiOBrxCl1-x　solid　solution　also　plays　an　important　role　in　the　CO2　reduction.　©　2018　Elsevier　B.V.
