Abstract

original image

Packings of carbon nanotubes with three and four different orientations of tube axes (one of such structures is displayed in the figure) are shown to be energetically and mechanically stable systems with outstanding hydrogen storage properties (total uptake amounts up to 19.0 wt% at 77 K and 5.5 wt% at 300 K) approaching the Department of Energy targets.
