Mechanistic exploration of g-C₃N₄ in facilitating the generation of high-quality Ag NWs.

Caption

Thermodynamic analysis reveals that penta-twinned Ag seeds, enclosed with 10 (111) facets, form preferentially in low-supersaturation solution due to their low facet energy and low chemical potential for bulk structure. This requirement can be satisfied by adding appropriate 2D materials (e.g., g-C3N4), which significantly suppresses random nucleation and allows the in-situ formation of high-purity seeds for growing high-quality Ag NWs.
