| 摘要 |
A method for producing nanoscaled carbon materials comprising providing, dispersed in a carrier gas, finely divided substrate particles on which to nucleate a catalyst, providing in said carrier gas a catalyst precursor material, decomposing the catalyst precursor material to form a catalytic metal in the presence of the substrate particles such that the catalyst metal is deposited on said substrate particles to form supported-catalyst particles dispersed in said carrier gas, forming a mixture of said dispersed supported-catalyst particles and a gas comprising a carbon containing gas at a temperature at which said carbon containing gas will react to form carbon when in the presence of said supported-catalyst particles, forming nanoscaled carbon materials by said carbon forming reaction and recovering the nanoscaled carbon materials.
