  Abstract

Two types of mesoporous carbons, CMK-3 and CMK-5, were prepared using mesoporous silica as a removable template, and their hydrogen storage capacities were evaluated. For the purpose of comparison, MWCNT (multi-walled carbon nanotubes) was selected and the adsorption of hydrogen was measured. The amount of hydrogen adsorbed on carbon materials was found to be closely related to the surface areas of carbon samples: The higher the surface area of the carbon material, the larger amount of hydrogen was adsorbed. The hydrogen storage capacity increased in the order of CMK-5 > CMK-3 > MWCNT. In addition, hydrogen storage capacity was greatly enhanced by the Pd-doping onto CMK-5. When the metallic Pd was doped on the carbon material, the adsorption amount of hydrogen via a hydrogen spill-over mechanism was crucial to the hydrogen storage capacity of Pd-doped CMK-5.
