A method for producing a material based on silicon nanowires is provided. The method includes the steps of: i) bringing into contact, in an inert atmosphere, a sacrificial support based on a halogenide, a carbonate, a sulfate or a nitrate of an alkali metal, an alkaline earth metal or a transition metal having metal nanoparticles, with the pyrolysis vapours of a silicon source having a silane compound, by which silicon nanowires are deposited on the sacrificial support; and optionally ii) eliminating the sacrificial support and recovering the silicon nanowires produced in step ii). |
