Hetero Atom Substituted Carbon-Potential Hydrogen Storage Materials

Nano-materials based on carbon have not shown promise so far for hydrogen storage application. The reason for this situation has been addressed in this presentation. Hetero-atom substituted carbon materials have been shown to exhibit sites responsible for dissociation of molecular hydrogen and its spill-over to carbon surface. Theoretical and experimental results on hetero atom substituted carbon materials have been assembled to verify this postulate. Phosphorus containing carbon materials have been prepared and its hydrogen sorption capacity (similar to 1%) has been evaluated.
