The effect of carbon nanotubes in increasing the hydrogen storage capacity

We use the molecular dynamics method to simulate hydrogen adsorption in finite bundles of single walled carbon nanotubes. We examine the effects of temperature,compression of gas, and nanotube diameter on increasing the capacity for hydrogen storage. To expand our conclusions, we extend our study to several different bundles including (4,4), (7,7), and (10,10) nanotubes. The study shows a significant increase in the hydrogen density near the surface of nanotubes. This increase is more pronounced in lower gas temperatures.
