چکیده
This review concentrates on the various chemical routes for synthesis of silver nanowires by soft solution methods, and also the production of gold nanotubes and Pt nanotubes from different templates. After a comprehensive comparison between the developed methods, it is concluded that the soft solution method has obvious advantages and is the most promising route for the mass production of silver nanowires. Herein its recent development is generalized into two groups: surfactant-assisted soft chemistry method and soft template method of which advantages and disadvantages will be discussed elaborately and separately. In addition, the synthesis of Au and Pt nanotubes from resultant silver nanowires, although less researched than other methods, is considered as the most convenient and facile route among the templated methods. Due to their high thermal and electrical conductivities, these metal nanomaterials are excellent candidates for the conductive filler in composite adhesive. Especially for one-dimensional metal nanostructures, they show great promise in the improvement of current conductive adhesive.

G replacement reactions between solid metal nanoparticles with oxidizing metal precursors represent a versatile strategy for synthesizing hollow metal nanostructures with tailored properties that are difficult (or even impossible) to achieve from their solid counterparts. For example, reactions of silver nanocubes with aqueous solutions of HAuCl4 enable the synthesis of hollow nanoboxes with se...
