Abstract: Plate-like metal nanomaterials have attracted great interest due to their shape anisotropy and large surface area. The synthesis of non-noble metal nanocrystals with high purity remains challenging, which limits their property studies and applications. This paper presents a selective etching mechanism that effectively facilitates the dissolution of non-target seeds during the synthesis of Cu nanoplates. This innovative approach not only enables the production of highly pure nanoplates but also allows for the shape transformation of nanoparticles into nanoplates. The resulting Cu nanoplates exhibit tunable localized surface plasmon resonance (LSPR) properties and highly enhanced performance in surface-enhanced Raman scattering (SERS). This work contributes to the shape-controlled synthesis of non-noble metal nanocrystals for a broad range of applications.
