Nitrene radical dopant was an effective addition required for enhancing the Pt binding on the graphene sheet. We found that up to three H2 molecules could be adsorbed by Pt-functionalized graphene with an average binding energy in the range 3.049?1.731eV eV. The most crucial part of our work is measuring the effect of nitrene radical on Pt-functionalized graphene. Our calculations predicted that the addition of NH radicals on Pt-functionalized graphene enhance the binding of Pt on graphene, which helps also to avoid the desorption of Pt(H2)n (n=1-3) complexes from graphene sheet. Our results also predict Pt-functionalized NH-doped graphene is a potential hydrogen storage medium for on-board applications. http://pubs.sciepub.com/ajn/7/1/4/ajn-7-1-4.pdf DFT H2 Pt-functionalized graphene hydrogen storage capacity NH radical
