Figure 9. Electrochemical reduction of CO₂ over 2D metal dichalcogenides. (A) PDOS for the spin-up channel of Mo atoms at the edge and within the lattice. (B) PDOS for the spin-up channel of the s, p, and d orbitals of Mo-edge atoms^[144]. (C) Schematic illustration of the synthesis of H-SnS₂ nanosheets. (D) TEM image of H-SnS₂ nanosheets. (E) HRTEM image of H-SnS₂ nanosheets. (F) XRD patterns of H-SnS₂ nanosheets. (G) Plot of current density vs. potential over SnS₂ and H-SnS₂ electrodes. (H) Structural model of H-SnS₂ nanosheets. (I) Plot of FE of products vs. potential over SnS₂ and H-SnS₂ electrodes^[148]. 2D: 2-dimensional; PDOS: projected density of states; TEM: transmission electron microscopy; FE: Faradaic efficiency.
