- Abstract
Electronic and geometric structure of Me30B60 {Me=Ti,Sc} noncarbon fullerenes is investigated by DFT calculations. The hydrogen adsorption values on the fullerene surfaces are calculated. It is shown that every metal atom in the fullerene can hold up to 2 hydrogen molecules. At that the value of the hydrogen adsorption energy is contained inside desirable interval 0.2-0.4 eV/(molecule H2) and the total amount of the hydrogen correspond to 5.4-5.6%(mass.). It is established that Sc30B60 fullerenes form the molecular crystal, but Ti30B60 fullerenes form the covalent crystal structures.
