Chem Commun (Camb). 2010 Nov 28;46(44):8422-3. doi: 10.1039/c0cc03810e. Epub 2010 Oct 11.

Abstract

Concave gold nanoplates are obtained in hexagonal liquid crystal (LLC) made of SDS (sodium dodecyl sulfate)/glycine/HAuCl(4) aqueous solution system where glycine plays the key role. All plates are single-crystals, characterized by {111} facets, with concave centers of regular hexagonal or triangular shapes, and with better electrocatalytic activity than gold nanoplates.
