Destabilization of gold clusters for controlled nanosynthesis: from clusters to polyhedra

Adv Mater. 2014 Jun 4;26(21):3427-32. doi: 10.1002/adma.201306167. Epub 2014 Mar 11.

Abstract

A precisely controlled destabilization of gold thiolate clusters is demonstrated to grow 12 {110}-faceted gold dodecahedra with greatly enhanced catalytic capability, and reveal the growth mechanism by DFT simulations. This greatly advances our understanding of nanocrystal growth and opens a new window for controlling the dissociation of clusters to produce nanocrystals with specific shapes.

Keywords: DFT; clusters; destabilization; growth; polyhedra.
