Production of single-walled carbon nanotubes

摘要

The present invention relates to a large-scale hydrogen arc discharge method for the synthesis of single-walled carbon nanotubes (SWNTs): Under the atmosphere of H2, a large-size anode composed of graphite powders, catalyst metals and growth promoter is consumed with the growth of SWNTs; The angle between the anode and cathode can be adjusted in the range of 30 DEG -80 DEG ; The catalysts used can be two or more kinds of metals selected from Fe, Co, Ni and Y, which have been proved to be essential for the growth of SWNTs; The proportion of catalysts is modified in the range of 2.5-5.0 at%. By these processes, large-scale SWNTs can be synthesized with the advantages of semi-continuous synthesis, low cost and high quality, and the SWNTs obtained can be then employed as a kind of promising hydrogen storage material. <IMAGE>
