Abstract
Silicon nanoparticles and methods for preparation of silicon nanoparticles are provided. Embodiments include a method for grinding silicon. Methods include providing silicon material, providing a grinding liquid including a polar solvent, and grinding the silicon material in the presence of the grinding liquid to yield silicon nanoparticles. Grinding the silicon in the presence of the grinding liquid can chemically functionalize the silicon material as the nanoparticles are formed to provide stable chemically functionalized nanoparticles.
