We have found that Li atom prefers to stay on the trigonal pole (TP) of \(\gamma\) -GNT whereas OLi 2 is strongly adsorbed on B atom of B, N-doped hexagonal ring site connected with acetylenic linkage, which is desirable for H 2 storage. In presence of a small polar molecule OLi 2 exploits the hydrogen storage ability more than that in the bare \(\gamma\) -GNT as well as the Li-adsorbed \(\gamma\) -GNT. The thermodynamical stability of hydrogen loaded \(\gamma\) - GNT is studied using binding energies, and change in reaction enthalpies. The maximum retrievable H 2 uptake predicted that eight H 2 molecules can be physically adsorbed in non-dissociated form per OLi 2 . The stability and reactivity of these hydrogen-adhered species are analyzed through the energy gap between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO). Exohedral CO sorption behaviour on Li-doped \(\gamma\) -GNT is also analyzed here
