Abstract
Nitrogen-doped graphene and carbon nanotubes were prepared and employed as additives to NaAlH4 to facilitate hydrogenation and dehydrogenation reactions. The decomposition behavior of carbon nanomaterial admixed NaAlH4 was studied by constant temperature desorption, differential scanning calorimetry and in situ FT-IR experiments. Carbon nanomaterials decrease the dehydrogenation temperature of NaAlH4 and enhance the dehydrogenation kinetics by lowering the activation energy. A reversible hydrogen storage of 1.8 wt% was achieved by the nitrogen-doped carbon nanotube/nitrogen-doped graphene admixed sodium aluminum hydride.
