Electrochemical removal of surfactants from Pt nanocubes

Abstract

A straightforward procedure for removing commonly used surfactants in nanoparticle synthesis, PVP and oleylamine/oleic acid, from Pt nanocubes by electrochemical potential cycling in 0.5 M NaOH is reported. The cyclic voltammetric results demonstrate that this procedure can effectively remove surfactants from Pt nanocubes, while preserving their surface structure.
