Abstract
The present invention relates to an advanced preparation method of organic-transition metal hydride used as hydrogen storage materials, the method including: preparing organic-transition metal-aluminum hydride complexes by reacting the organic-transition metal halide with metal aluminum hydride compounds; and preparing the organic-transition metal hydride by reacting the organic-transition metal aluminum hydride complexes with Lewis bases. Since the preparation method of the organic-transition metal hydride according to the present invention does not use catalysts, it has advantages that it does not cause problems due to poisoning and can prepare the organic-transition metal hydride at high yield under less stringent conditions. The hydrogen storage materials containing the organic-transition metal hydride prepared from the preparation method can safely and reversibly store a large amount of hydrogen.
