Magnesium-based hydrogen storage materials are considered to be one of the most promising solid-state hydrogen storage materials due to their large hydrogen storage capacity and low cost. However, slow hydrogen absorption/desorption rate and excessive hydrogen absorption/desorption temperature limit the application of magnesium-based hydrogen storage materials. The present paper reviews recent progress in improving the hydrogen storage properties by element substitution and additives. Ball milling is the promising technology for preparing magnesium-based hydrogen storage materials. The research and development of approaches for modifying magnesium-based hydrogen storage materials prepared by ball milling is systematically expounded. It is concluded that ball milling can significantly improve the kinetic and electrochemical properties of magnesium-based hydrogen storage materials and increase the hydrogen storage capacity. In the future, the research of magnesium-based hydrogen storage materials should be developed in terms of hydrogen storage mechanism, computer design of materials and development of a more optimized catalytic system.

The paper mainly focuses on the ability of absorbing hydrogen molecule of the dimetallocene (C5H5)2TM2(TM=Ti/Zn/Cu/Ni) based on the first-principles calculation. The result indicates that these compounds can adsorb up to eight hydrogen molecules, the binding energy is 0.596eV/H2 for Cp2Ti2, 0.802eV/H2 for Cp2Zn2, 0.422eV/H2 for Cp2Cu2 and 0.182eV/H2 for Cp2Ni2 respectively. The corresponding gravimetric hydrogen-storage capacity is 7.1wt% for Cp2Ti2, 6.2wt% for Cp2Zn2, 6.3wt% for Cp2Cu2 and 6.5wt% for Cp2Ni2 respectively. These sandwich-type organometallocenes proposed in this work are favorable for reversible adsorption and desorption of hydrogen under ambient conditions. These predictions will likely provide a new route for developing novel high-capacity hydrogen-storage materials.
