Résumé

In order to interpret adsorption results of hydrogen storage by adsorption in graphite nanofiber (GNF) materials at molecular scale and to propose optimized structures of graphitic materials, we have realized both experimental and numerical studies of gas adsorption in GNF. The porous materials have been synthesized by CVD method. The adsorption experiments were performed at 293 K by a volumetric method at high pressure until 40 MPa. We completed the surface reactivity analysis by performing structural characterizations of the samples using different structural techniques and numerical modelling computed in the grand canonical Gibbs ensemble. Within the cell, stacks of plans of graphite are arranged periodically using boundary conditions. The present numerical approach enables to interpret the results based on the solid-gas molecular interactions reactivity analysis. (c) 2008 International Association for Hydrogen Energy.
