Photocatalytic　reduction　of　CO2　to　produce　valuable　chemicals　can　simultaneously　reduce　the　greenhouse　effect　and　relieve　the　energy　shortage　pressure.　However,　CO2　reduction　over　semiconductor-based　photocatalysts　usually　generates　C1　products.　In　this　manuscript,　we　reported　the　preparation　of　a　Cu2O/Cu　nanocomposite　for　photocatalytic　CO2　reduction　under　visible　light.　Since　Cu2O　has　a　narrow　band　gap,　photocatalytic　CO2　reduction　over　the　as-obtained　Cu2O/Cu　was　carried　out　in　the　presence　of　benzyl　alcohol　as　the　sacrificial　agent　to　inhibit　the　possible　oxidation　of　Cu+　by　the　photo-generated　holes　and　to　complete　the　photocatalytic　cycle　over　Cu2O.　It　was　found　that　benzyl　acetate,　instead　of　C1　products,　was　generated　as　the　main　product　over　Cu2O/Cu,　which　can　be　ascribed　to　a　successful　coupling　of　CO2　reduction　and　benzyl　alcohol　oxidation　promoted　by　metallic　Cu.　After　reaction,　metallic　Cu　in　Cu2O/Cu　was　oxidized　to　CuO,　which　led　to　the　deactivation　of　the　catalyst.　However,　the　catalyst　can　be　regenerated　by　reduction　to　recover　its　performance　for　producing　benzyl　acetate.　The　strategy　by　coupling　photocatalytic　CO2　reduction　with　the　oxidation　of　organics　not　only　can　lead　to　valuable　multi-carbon　organics　from　CO2　reduction,　but　also　can　be　used　to　inhibit　the　photo-corrosion　of　narrow-band　gap　semiconductor-based　photocatalysts　during　photocatalytic　reactions.
