This paper describes a new solution route for the preparation of silicon nanoparticles functionalized at the surface using potassium incorporated in graphite (C8K) as reducing agent of silicon tetrachloride (SiCl4). In a first step, chloride,capped silicon nanoparticles were obtained. They allowed an easy access, in a second step, to a range of surface functionalities by simple nucleophilic substitutions: hydroxy, alkyl, alkoxy or amino groups. They were characterized by FTIR, 1H, 13C and 29Si NMR. A mean diameter of 13 nm was found for these particles. © 2007 Académie des sciences.
