Synthesis and Size Control of Pt Nanocubes with High Selectivity Using the Additive Effect of NaI

Abstract

Abstract The synthesis and size control of Pt nanocubes stabilized by polyacrylic acid sodium salt (PAA) were carried out by varying the reaction temperature and the growth rate between the {111} and {100} faces with the addition of NaI; the shape selectivity was about 70–80% and the cubic size was controllable between 7.5–10.5 nm.
