Abstract
A fluffy nano-material and method of manufacture are described. At 2000× magnification the fluffy nanomaterial has the appearance of raw, uncarded wool, with individual fiber lengths ranging from approximately four microns to twenty microns. Powder-based nanocatalysts are dispersed in the fluffy nanomaterial. The production of fluffy nanomaterial typically involves flowing about 125 cc/min of organic vapor at a pressure of about 400 torr over powder-based nano-catalysts for a period of time that may range from approximately thirty minutes to twenty-four hours.
Claims12
A nanomaterial comprising:
- a metal powder support material selected from a group consisting of Sc, Ni, Fe, Cr, Co, Ti, V, Mn, Cu, Zn, Y, Zr, Nb, Ru, Rh, Pd, Hf, Ta, W, Re, Ir, Pt, Au, Ce, Th, and U containing metals, alloys, and intermetallics thereof;
- nanoparticles formed on a surface of the metal powder support material;
- and
- carbon nanotubes anchored directly to the surface of the metal powder support material and anchored directly to the nanoparticles on the surface of the metal powder support material,
- wherein the metal powder support material acts as a catalyst for growing the carbon nanotubes at least in part directly from the surface of the metal powder support material such that the carbon nanotubes are anchored directly to the surface of the metal powder support material,
- wherein the nanoparticles act as a separate catalyst for growing the carbon nanotubes at least in part from the nanoparticles such that the carbon nanotubes are anchored directly to the nanoparticles on the surface of the metal powder support material, and
- wherein the metal powder support material includes support particles having a diameter of less than 100 microns.
