In this work, a facile method has been developed to fabricate Au nanoplates in one step through heating formaldehyde and HAuCl 4 aqueous solution. The obtained Au nanoplates are single crystal with an average edge length of approximately 160 nm. And the formation of plate-like Au nanostructures is because of the adsorption of formaldehyde on the surfaces of Au nanostructures, leading to a similar surface energy of {111} and {100} facets.
