Abstract
A marigold-like SiC@MoS2 nanoflower with a unique Z-scheme structure efficiently achieves the overall conversion of gas phase CO2 with H2O (CO2 (g) + 2H(2)O (g) = CH4 + 2O(2)) without any sacrificial reagents under visible light (lambda >= 420 nm) irradiation. The CH4 and O-2 evolution are 323 and 621 mu L-g-(1).h(-1), and stable throughout 5 cycle reactions of total 40 h. This work demonstrates a breakthrough in artificial photosynthesis with the Z-scheme 1D heterojunction constructed by combining 2D semiconductor and 3D semiconductor based on the transfer balance of photogenerated electron and hole.Funding Information
