Solution-phase synthesis of metal nanocrystals with multiple additives is a common strategy for control over nanocrystal shape, and thus their properties. However, few rules are available to predict the effect capping agents on shapes, making it hard rationally design synthetic conditions. This work uses combination seed-mediated growth, single-crystal electrochemistry, DFT calculations determine roles PVP Cl- in anisotropic growth penta-twinned silver nanocrystals. Single-crystal seeds grow...
The application of capping agents to modulate the colloidal synthesis metal nanocrystals offers an effective avenue for shape control, but roles such are not yet completely understood. This study uses seed-mediated growth, single-crystal electrochemistry, and surface-enhanced Raman spectroscopy (SERS) illuminate polyvinylpyrrolidone (PVP) bromide (Br–) in anisotropic growth Ag nanocubes. Synthetic results show that nanocubes only form presence both PVP sufficiently high concentrations Br–....
