Hydrogen physisorption on Single Walled and Double Walled Carbon Nanotubes

Due to the light mass and large exposed surface of carbon nanotubes, these materials have been the focus of tremendous efforts, including experiments and theoretical investigations[1-2] in the field of energy storage applications. In a general classification, the parameters that have been considered to achive the optimum condition of physisorption can be stored to the structural and operational ones. The most investigated parameters in the literature are diameter and the Van der Wals gap between the tubes in a bundle of the structural parameters, and the applied pressure, temperature and the amount of loading are of the operational parameters
