Abstract
Methods for producing nanostructures from copper-based catalysts on porous substrates, particularly silicon nanowires on carbon-based substrates for use as battery active materials, are provided. Related compositions are also described. In addition, novel methods for production of copper-based catalyst particles are provided. Methods for producing nanostructures from catalyst particles that comprise a gold shell and a core that does not include gold are also provided.
Claims21
A method for producing nanostructures, the method comprising:
- providing a porous substrate having catalyst particles disposed thereon, which catalyst particles comprise copper, a copper compound, and/or a copper alloy;
- and
- growing the nanostructures from the catalyst particles in a reaction vessel;
- wherein the substrate is a population of graphite particles having the catalyst particles disposed thereon, and the nanostructures are silicon nanowires grown by a vapour-solid-solid or a vapour-liquid-solid synthesis technique, and
- wherein the population of graphite particles form a packed bed in the reaction vessel in which the nanostructures are grown.
