摘要： A method of purifying a single-walled carbon nanotube catalytic product having the steps of providing a catalytic product including single-walled carbon nanotubes, and a Group VIII and/or Group VIb transition metal, exposing the catalytic product to a heated oxidative gas to provide a treated carbon nanotube product including single-walled carbon nanotubes and the Group VIII and/or Group VIb transition metal, and exposing the treated carbon nanotube product to an acid to separate the single-walled carbon nanotubes from the Group VIII and/or Group VIb transition metal. The catalytic product may include a support material and amorphous carbon.

摘要： A method of producing a carbon nanotube product comprising a catalytic particle and single-walled carbon nanotubes deposited thereon. The catalytic particles preferably contain at least one metal from Group VIII, including for example Co, Ni, Ru, Rh, Pd, Ir, and Pt, and at least one metal from Group VIb including for example Mo, W and Cr. The catalytic particle preferably further comprises a support material such as silica. The carbon nanotube product is preferably formed by exposing the catalytic particle to a carbon-containing gas at a temperature sufficient to form the single-walled nanotubes as a primary portion of a solid carbon product on the catalytic particles.

摘要： A method and apparatus for catalytic production of carbon nanotubes. Catalytic particles are exposed to different process conditions at successive stages wherein the catalytic particles do not come in contact with reactive (catalytic) gases until preferred process conditions have been attained, thereby controlling the quantity and form of carbon nanotubes produced. The method also contemplates methods and apparatus which recycle and reuse the gases and catalytic particulate materials, thereby maximizing cost efficiency, reducing wastes, reducing the need for additional raw materials, and producing the carbon nanotubes, especially SWNTs, in greater quantities and for lower costs.
