摘　　要：Bamboo-like carbon nanotubes were prepared by decomposing C_2H_2 on ferric catalyst. Acid immersion, ball milling and KOH etching were performed before hydrogen adsorption measurement. TEM, HREM, SEM and IR analyses were used to characterize the microstructure. The maximum hydrogen adsorption capacity of the raw sample reached 1.53% (mass) at 300 K under 7 MPa. The unusual structure of carbon nanotubes plays a dominant role for hydrogen adsorption. But some treatments will destroy the structure and decr...Bamboo-like carbon nanotubes were prepared by decomposing C_2H_2 on ferric catalyst.
