Abstract: The process of bi-functionalizing silicon nanoparticles and bi-functionalized silicon nanoparticles are described. The processes include applying shear forces to silicon metal in the presence of an alkane, thereby providing an alkyl-hydride-functionalized silicon nanoparticle, which is then treated with a reactant, e.g., a compound that reacts with the hydride functionality, to provide the bi-functionalized silicon nanoparticles. The resulting product can include a plurality of functionalities on a silicon nanoparticle derived from alkenes, alkynes, aldehydes, alcohols, thiols, amines, carboxylates, and/or carboxylic acids.

Abstract: The mechanochemical functionalization of silicon nanoparticles and functionalized silicon nanoparticles are described. The processes include applying shear forces to silicon metal the presence of an alkane and thereby functionalizing the silicon with an alkyl-functionalization, preferably an alkyl-hydride-functionalization. The resulting product includes a plurality of silicon nanoparticles each carrying an alkyl-functionalization, and preferably a hydride-functionalization, derived from an alkane.
