Group IVA functionalized particles and methods of use thereof

摘要

Disclosed are functionalized Group IVA particles, methods of preparing the Group IVA particles, and methods of using the Group IVA particles. The Group IVA particles may be passivated with at least one layer of material covering at least a portion of the particle. The layer of material may be a covalently bonded non-dielectric layer of material. The Group IVA particles may be used in various technologies, including lithium ion batteries and photovoltaic cells.

1. A method of functionalizing a Group IVA particle, the method comprising:
a) reducing the size of a Group IVA particle; b) treating the Group IVA particle with a protic acid to provide a hydrogen passivated Group IVA particle; and c) treating the hydrogen passivated Group IVA particle with a compound to provide a passivated Group IVA particle, said particle passivated with a non-dielectric layer covering at least a portion of a surface of the Group IVA particle.
