Abstract

The invention provides a preparation method of Ag2E nano wire, wherein, E is sulfur, or selenium and or tellurium, and the method is characterized by comprising following steps: (1) preparing materials: adding silver nitrate into a beaker containing deionized water, adding alkali, a complexing agent and a template in sequence, stirring for fully dissolving, then adding a compound containing sulfur, or selenium, or tellurium, finally adding a reducing agent, and stirring until fully dissolving; wherein, silver nitrate and the compound containing sulfur, or selenium, or tellurium are added according to the atomic ratio 2:1, and the concentration of the silver nitrate is 0.01 mol / L-0.08 mol / L; (2) carrying out a constant temperature reaction; (3) washing; (4) drying. The invention has the advantages of cheap and easily available raw materials, simple technology and easy realization of large scale production. The synthesized silver sulfide, silver selenide and silver telluride nano wire can be widely applied to fast ion conductors, nonlinear optical devices, photoelectric secondary batteries, multifunctional ion selective electrodes, phase change storage devices, thermoelectric devices, magnetic field detectors, etc.
