Figure 5. 2D materials as homogenous nucleation sites. (A, B) Deposition mechanism with pure Zn and VSe₂-coated Zn substrate. The rapid diffusion of Zn adatoms on the VSe₂ substrate results in ordered layer-by-layer Zn electrodeposits, which possess a higher portion of the (002) facets. SEM images of deposition morphology on (C, D) bare Zn and (E, F) VSe₂-coated Zn. Reproduced with permission^[144]. Copyright 2022, Wiley-VCH GmbH. Potential competitive reaction pathways of Zn deposition on both (G) the basal plane and (H) the edges of a MoS₂ substrate. The basal plane of the mono-oriented MoS₂ substrate effectively guides the non-dendrite Zn deposition. Reproduced with permission^[146]. Copyright 2023, Wiley-VCH GmbH.
