Hydrogen storage utilizing carbon nanotube materials

摘要

A material for the storage of hydrogen is provided comprising single wall carbon nanotubes (SWNT), wherein the majority of the diameters of the single wall carbon nanotubes of the assembly range from 0.4 to 1.0 nanometers (nm), and the average length is less than or equal to 1000 nm, or the diameters of the single wall carbon nanotubes of the assembly range from 0.4 to 1.0 nanometers (nm), and the heat (-DeltaH) of hydrogen adsorption of the material is within the range from 4 kcal/mole H₂ to 8 kcal/mole H₂. Processes for the storage and release of hydrogen using the materials are disclosed.
