Octahedrally shaped noble‐metal nanocrystals are fascinating for their unique properties, such as electrocatalytic, catalytic, plasmonic, and optical behavior, owing to their exclusively exposed {111} facets; O h symmetric structure; and close‐packed surface atoms in low‐index surface categories, which are normally stable in a reaction. A series of protocols in the preparation of noble‐metal nano‐octahedra through a wet‐chemical synthetic strategy have been developed in recent years. Herein, advances in synthetic approaches and mechanistic studies of noble‐metal nano‐octahedra are systematically discussed and key factors, including reduction kinetics, selective capping, and epitaxial growth, are outlined. Their unique performance as advanced electrocatalysts towards fuel‐cell reactions is highlighted as well.
