Mimicking　natural　photosynthesis　to　convert　CO2　and　H2O　into　highly　valuable　solar　fuels　is　one　of　the　ideal　ways　to　alleviate　the　energy　shortage　and　environmental　pollution.　However,　the　low　mobility　of　photogenerated　holes　and　sluggish　H2O　oxidation　half　reaction　seriously　retard　the　reduction　efficiency　of　CO2　by　photocatalysis.　In　this　paper,　we　reported　that　the　visible　light-active　SiC　photocatalyst　was　inserted　into　the　InVO4　nanoflower　framework　to　form　the　dual　Z-scheme　heterojunction　composited　photocatalyst.　The　composited　photocatalysts　can　not　only　neutralize　the　low　mobility　of　photogenerated　holes　on　SiC　but　also　improve　the　H2O　oxidation　on　InVO4　nanoflowers.　This　leads　to　an　effective　conversion　of　CO2　to　CO　without　sacrificial　agents　under　visible　light　irradiation　as　well　as　a　good　separation　of　photogenerated　charge　carriers　in　the　composited　photocatalyst　for　the　subsequent　reaction.　In　comparison　to　the　parent　InVO4　and　SiC,　the　optimum　CO　yields　over　InVO4/SiC　were　9.41　and　11.54　times,　respectively.　Under　3　h　visible　light　irradiation,　the　yields　of　CO　reach　up　to　142.6　mu　molg(-1)　and　stability　of　O-2　release　over　InVO4/SiC.　This　research　offers　a　practical　approach　to　developing　an　efficient　photocatalyst　for　the　conversion　of　CO2　with　H2O.
