Fig. 5.

(A to F) Au3Cu nanoparticles assembled on Si nanowire arrays, reproduced with permission from Kong et al. (71). (A) Schematic of the nanoparticle deposition; (B) linear sweep voltammetry (LSVs) and faradaic efficiencies toward CO production; and (C to F) SEM and corresponding elemental mapping of Cu (D), Au (E), and Si (F). Scale bars 200 nm. (G to I) Si|Cu photocathodes for multicarbon production, reproduced with permission from Kempler et al. (69). (G) False-color SEM image and (H and I) PEC performance. (J to L) Cu2O|SnOx photocathode, reproduced with permission from Zhang et al. (113). (J) Schematic depiction and (K and L) PEC activity. (M to O) Cu nanoparticles on Si nanowires for selective ethylene synthesis, reproduced with permission from Roh et al. (111). (M) Schematic of the Si nanowire/Cu nanoparticles assembly, (N) faradaic efficiencies, and (O) stability test.
