摘要：

Metal nanomaterials have excellent properties superior to corresponding bulk materials. The directional growth of macro-area metal nanostructures cannot be obtained due to the limitation of synthesis methods. Solid-state ionics method can prepare ideal nanostructures by effectively controlling the morphology of surface, length, order degree and surface roughness of nanostructures. Firstly, the preparation mechanism of solid-state ionics method is reviewed. Secondly, the preparation process of single metal nanostructures and the effects of electric field strength, electric current and types of fast ionic conductor films on the morphology and order degree of nanostructures are introduced. Then, the preparation techniques of different alloy nanostructures and composite nanostructures are summarized. Moreover, different factors affecting the detection sensitivity are summarized by comparing the limiting concentrations of different nanostructures as surface enhanced Raman scattering (SERS) substrate. Finally, the problems in this field are summarized and the future research trend of this method is prospected. © 2020, Editorial Office of FINE CHEMICALS. All right reserved.
