Seeing Is Believing: How Does the Surface of Silver Nanocubes Change during Their Growth in an Aqueous System

The seed-mediated growth involving cetyltrimethylammonium chloride (CTAC), silver trifluoroacetate (CF3COOAg), ascorbic acid (H2Asc), and Ag seeds covered by poly(vinylpyrrolidone) (PVP) in aqueous medium is a robust route to nanocubes with tunable sizes. However, mechanistic details such as changes the surface remain elusive. Herein, we address this issue leveraging high sensitivity water compatibility of surface-enhanced Raman scattering (SERS). Our results reveal that addition CTAC ligand exchange between PVP further introduction CF3COOAg leads deposition AgCl on seeds. H2Asc subsequently introduced increases electron density due transfer, manifested rapid pronounced enhancement SERS signals from CTA+. electrons also enable reduction directly transform contact into atoms enlarge nanocubes.
