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) + 2H₂O (g) = CH₄ + 2O₂) without any sacrificial reagents under visible light (λ ≥ 420 nm) irradiation. The CH₄ and O₂ evolution are 323 and 621 μL·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.
