Adsorption of hydrogen at 300 K has been investigated on well-characterized samples of carbon nanotubes,
besides carbon fibres by taking care to avoid many of the pitfalls generally encountered in such measurements.
The nanotube samples include single- and multi-walled nanotubes prepared by different methods, as well as
aligned bundles of multi-walled nanotubes. The effect of acid treatment of the nanotubes has been examined. A
maximum adsorption of ca. 3.7 wt% is found with aligned multi-walled nanotubes. Electrochemical hydrogen
storage measurements have also been carried out on the nanotube samples and the results are similar to those
found by gas adsorption measurements.
