Abstract
A process for the production of carbon nanostructures by an oxidation-reduction method is described. The growth of carbon nanorods, nanotubes, and nanoclusters on planar and non planar substrates, and free standing is demonstrated. In one embodiment a reactive gas is generated in situ and reacted with a carbide while the byproducts are removed, thereby adjusting the equilibrium to favor the formation of the carbon nanostructured product.
Claims32
A process for producing carbon nanostructures which comprises the steps of:
- introducing a reactive gas into a reaction chamber containing a carbide substrate;
- reacting the reactive gas with the carbide substrate by a reaction that converts carbon in the carbide to elemental carbon nanostructures and produces a gaseous byproduct;
- and
- removing the gaseous byproduct from the reaction chamber in a manner that shifts the reaction equilibrium to favor the formation of the carbon nanostructures.
