Abstract
A marigold-like SiC@MoS 2 nanoflower with a unique Z-scheme structure efficiently achieves the overall conversion of gas phase CO 2 with H 2 O (CO 2 (g) + 2H 2 O (g) = CH 4 + 2O 2 ) without any sacrificial reagents under visible light (£f ? 420 nm) irradiation. The CH 4 and O 2 evolution are 323 and 621 £gL¡Pg -1 ¡Ph -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. ? 2018 American Chemical Society.
