Synthesis of Trisoctahedral Gold Nanocrystals with Exposed High‐Index Facets by a Facile Chemical Method

The many faces of gold: Trisoctahedral gold nanocrystals have been synthesized in a high yield for the first time. Electron diffraction and electron microscopy demonstrate that the nanocrystals are enclosed by 24 high-index facets, such as {221} planes (see SEM image (left) and model (right)).
