Hydrogen storage on highly porous novel corn grain-based carbon monoliths

The hydrogen (H-2) adsorption capacity of the highly porous novel corn grain-based carbon monoliths (CG-CMs) was assessed. The obtained H-2 adsorption results at 77 K (up to I bar) and 298 K (50 up to bar) were presented in the mass basis as well as in the volume basis. In addition, the mass basis and volume basis H-2 adsorption capabilities of the prepared carbon monoliths were correlated with their corresponding physical properties. Particularly, the influence of piece density on the volumetric H-2 capacity was discussed in detail. It was found that the H-2 adsorption abilities of the prepared CG-CMs are similar or higher than the other superactivated carbons or carbon monoliths. (C) 2009 Elsevier B.V. All rights reserved.
