4. Summary
Various CNT samples, including SWCNTs and MWCNTs, with
and without post-treatments, were employed for hydrogen
storage measurements by a volumetric method with a specifically-
designed equipment. Under a hydrogen gas pressure of
about 12 MPa and room temperature, the hydrogen storage
capacity of CNTs is less than 1.7 wt.%. These results suggest
that CNTs only have a hydrogen storage capacity far below
the DOE benchmark and be impractical for on-board hydrogen
uptake systems. On the other hand, CNTs may be used
as an effective additive in other hydrogen storage material
systems such as metal hydrides or complex compounds by
significantly improving their kinetics and capacity. |
