| Abstract: | One-dimensional nanomaterials possess excellent size effect. One-dimensional noble metallic materials display special physical and chemical properties different from corresponding block materials. In this paper，the main methods for the synthesis of controllable one-dimensional noble metallic nanomaterials in recent years were summarized，including template method，polyhydric alcohol revert method，chemical electricity deposited method，metal catalyzed reduction method，and the synthesis methods and mechanisms of one-dimensional noble metallic structures were focused on. With the emphasis on noble metals，such as silver and palladium，the mechanisms for the growth of controllable one-dimensional structures in shape were discussed，and the potential applications of gold and silver one-dimensional nanomaterials in the field of functional materials and biomedicine were also introduced. It is indicated that establishing new theories and methods for the preparation of one-dimensional metallic nano structures in preparation science，together with the model for the nucleation and growth kinetics shall be the focus in further research. |
