| It is reviewed the recent progress on the preparation of special-shaped metal nanomaterials including wires, rods, cubes, prisms, disks, and dendrites via chemical reduction in the presence of polymers or surfactants under the mild conditions. These polymers and surfactants act as capping agents or induce agents to control the anisotropic growth of metal crystals. It is found that many metal nanomaterials including silver, gold, copper, and other kinds of metal like platinum, lead, iron can be prepared via this approach. The growth mechanisms of special-shaped crystal are discussed detailedly. The application of resultant special-shaped metal nanomaterials is introduced briefly. Finally, we supply some personal perspectives on the future development of chemical preparation of special-shaped metal nanomaterials in soft solution. |
