A novel top-down procedure for synthesis of stable passivated nanoparticles uses a one-step mechanochemical process to form and passivate the nanoparticles. High-energy ball milling (HEBM) can advantageously be used to mechanically reduce the size of material to nanoparticles. When the reduction of size occurs in a reactive medium, the passivation of the nanoparticles occurs as the nanoparticles are formed. This results in stable passivated silicon nanoparticles. This procedure can be used, for example in the synthesis of stable alkyl- or alkenyl-passivated silicon and germanium nanoparticles. The covalent bonds between the silicon or germanium and the carbon in the reactive medium create very stable nanoparticles.

L'invention concerne un nouveau procédé descendant pour la synthèse de nanoparticules passivées stables utilisant un procédé mécano-chimique en une seule étape pour former et passiver les nanoparticules. Un broyage à billes haute densité (HEBM) peut être utilisé avantageusement pour réduire mécaniquement la dimension d'un matériau à des nanoparticules. Lorsque la réduction de taille survient dans un milieu réactif, la passivation des nanoparticules survient lorsque les nanoparticules sont formées. Ceci a pour résultat des nanoparticules de silicium passivées stables. Ce procédé peut être utilisé par exemple dans la synthèse de nanoparticules de silicium et de germanium passivées par alkyle ou alcényle stables. Les liaisons covalentes entre le silicium ou le germanium et le carbone dans le milieu réactif créent des nanoparticules très stables.
