The study on the hydrogen storage capability of large diameter SWCNT(10, 10), graphene and C60 functionalized with borane in shown. The SWCNT (10, 10) -BH3 is able to adsorb 6.12wt.% of hydrogen with optimum binding energy. While, both graphene and C6o functionalized with borane are found not to be suitable for hydrogen storage materials. The planar structure of graphene is not conducive for the functionalization with borane and hydrogen storage. While, the interaction between BH3 and C60 is such that the borane molecule is dissociatively absorbed. But, the interaction with hydrogen molecules is found to be repulsive and hence C60-BH3 is not eligible for hydrogen storage. The interaction between BHs and the carbon nanostructures strongly depends on the curvature of C-C bonds in these systems.
