Abstract
The present invention relates to a more advanced preparation method of organic-transition metal hydride as a hydrogen storage material, precisely a more advanced preparation method of organic-transition metal hydride containing aryl or alkyl group that facilitates safe and reverse storage of massive amount of hydrogen. The present invention relates to a preparation method of an organic-transition metal hydride comprising the steps of preparing a complex reducing agent composition by reacting alkali metal, alkali earth metal or a mixture thereof and (C10-C20) aromatic compound in aprotic polar solvent and preparing organic-transition metal hydride by reacting the prepared complex reducing agent composition and organic transition metal halide. The method of the present invention has advantages of minimizing the numbers and the amounts of byproducts by using a complex reducing agent and producing organic-transition metal hydride safely without denaturation under more moderate reaction conditions.
