Hydrogen Adsorption on Ru-Encapsulated, -Doped and -Supported Surfaces of C<sub>60</sub>

Hydrogen is considered as one of the promising clean energy sources for future applications including transportation. Nevertheless, the development of materials for its storage is challenging particularly as a fuel in vehicular transport. In the present study, density functional theory simulations f...
