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

The hydrogen (H2) adsorption capacity of the highly porous novel corn grain-based carbon monoliths (CG-CMs) was assessed. The obtained H2 adsorption results at 77 K (up to 1 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 H2 adsorption capabilities of the prepared carbon monoliths were correlated with their corresponding physical properties. Particularly, the influence of piece density on the volumetric H2 capacity was discussed in detail. It was found that the H2 adsorption abilities of the prepared CG-CMs are similar or higher than the other superactivated carbons or carbon monoliths.
