Hydrogen storage carbon adsorbents

CNTs possess interesting physical properties. Thermal conductivity of CNTs is in excess of2000 w/m/K. They have unique electronic properties. Applications include electromagnetic shielding, electron field emission displays for computers and other high-tech devices, photovoltaics, super capacitors, batteries, fuel cells, computer manory, carbon electrodes, carbon foams, actuators, material for hydrogen storage, and adsorbents.

Active carbon (AC), carbon nanotubes, carbon fibers, and other carbonaceous adsorbents, owing to their low atomic weight, high surface area, pore volume, and suitable mechanical properties, are excellent options as adsorbents for hydrogen storage [81,147,165-184],... 

Carbon adsorbs the undissociated hydrogen molecules by repulsion and dispersion forces at then-pore network and surface [2], However, since these binding forces are weak, the physical adsorption process at room temperature is virtually restrained by the thermal motion thus, to store large quantities of hydrogen, the carbon samples have to be cooled [166], However, a cryogenic hydrogen storage technique is, in the majority of cases, economically ineffective [173],...
