Abstract

Single- and multi-wall carbon nanotubes synthesized by catalytic decomposition of methane and acetylene, respectively were studied for their hydrogen adsorption capacity in their hollow and on their outer surface. The hydrogen storage capacity of the samples was measured for pressures 0-9 bar at 295 K and at 77 K. The results at different temperatures on the crude sample (closed tubes 10-50 μm long), on the purified sample (open tubes 10-50 μm long) and on the purified and broken sample (open tubes 0.1-0.7 μm long) show that breaking the nanotubes allows one to adsorb hydrogen in their hollow. In addition, the relative amounts of hydrogen adsorbed in the hollow and outer parts of the nanotubes can be distinguished.
