摘要
We report the results of our first principle calculation based on density functional theory on CnNaAlH4 complexes for n = 28, 32, 36, 40, 44, 50 and 60 to investigate the effect of curvature of small carbon fullerenes on hydrogen release from metal hydrides. The NaAlH4 molecule is found to interact weakly with all fullerenes considered. The hydrogen release energy is found to decrease significantly from 3.82 eV in NaAlH4 molecule to 2.46 eV, 2.82 eV, 2.53 eV, 2.14 eV, 2.89 eV, 2.21 eV, 3.20 eV in C28NaAlH4, C32NaAlH4, C36NaAlH4, C40NaAlH4, C44NaAlH4, C50NaAlH4 and C60NaAlH4 respectively.
