Many novel properties are beyond traditional theories when the materials are nanosized. All these may reasonably make nanomaterials become the representative of modern science and technology and the potential research hot. The noble metal nanomaterials have become one of the most active branches in nanomaterials area because of their distinct catalytic, electronic, magnetic, and luminescent properties. In this paper, the preparation methods and the applications of the noble metal nanomaterials are reviewed. In addition, the prospect is made.
