Description

Polyvinylpyrrolidone (PVP) is a widely used soluble polymer that is used in the production of nanoscale colloidal metal particles. The shape of the nanoparticles produced using this route is controlled by the interaction of the polymer and the functional groups of its monomer units with the facets of the growing nanoparticles. In this work we have used the sensitivity of cyclic voltametry to metal surface Miller index to understand the relative affinity of PVP for (111) and (100) facets of single crystal Pt surfaces. This is coupled with DFT calculations that reveal the preference of the monomer units for the various surface sites. This shows that the PVP interaction with the (100) surface is considerably stronger than with the (111), shedding light on the origins of morphological control for nanoparticle synthesis.
