Shape-Controlled Synthesis of Ag Nanocubes with Uniform Size

Abstract:

The controllable synthesis of special shape of nanoparticles with uniform size was most important for some special applications. In this work, we prepared silver nanocubes by Na₂S-mediated polyol synthesis using AgNO₃ as precursor, polyvinyl pyrrolidine(PVP) as capping agent and ethylene glycol(EG) as solvent and reductant under the protection of Ar characterized by SEM, UV-vis, DLS and Zeta potential. Silver nanocubes were successfully controllably obtained via optimizing the reaction conditions, such as the rate of Ar initially after 50 min pre-heating and subsequently after the addition of AgNO₃ solution，the volume of 3 mM Na₂S solution. The results showed that silver nanocubes with edge length of 50 nm and sharp corners were achieved at 230μL 3mM Na₂S solution added under a Ar rate of 1000 ml/min.
