摘要：
Density functional theory methodology has been used to study the adsorption of hydrogen molecule on transition metal doped fullerenes, namely, C19Fe and C19Co. The calculated hydrogen adsorption energy of the host fullerenes, C19Fe and C19Co comes well within the required range of average hydrogen adsorption energy. In addition to this, changes in the structural properties of the hosts also take place due to hydrogen adsorption. Finally, we have investigated the change in the electronic properties of the host fullerenes as a result of hydrogen adsorption on them and found that adsorption of hydrogen tunes the hosts' energy gap. Hence, these systems may also be used in the nanoelectronic application, where energy gap tuning is used.
