摘要:
A method for producing a single-walled carbon nanotube product by a hydrogen arc discharge method includes providing an anode including graphite powder, catalyst metal, and a growth promoter in an atmosphere containing hydrogen; providing a cathode in the atmosphere; and inducing an electric arc across the anode and cathode to thereby consume the anode and produce the single-walled carbon nanotube product. Additionally, the single-walled carbon nanotube product may be soaked in an acid or an oxidative reactant and heated under vacuum to produce a hydrogen storage material.
