Preparation method of organic-transition metal hydride complexes containing aryl group or alkyl group as hydrogen storage materials

摘要

The present invention relates to an improved preparation method of an organic-transition metal hydride as a hydrogen storage material, especially an improved preparation method of an organic-transition metal hydride containing aryl or alkyl group that facilitates safe and reversible storage of a massive amount of hydrogen. The present invention also 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 a C10 to C20 aromatic compound in aprotic polar solvent; and preparing the organic-transition metal hydride by reacting the prepared complex reducing agent composition with an organic-transition metal halide in the absence of a hydrogen source. The method has the advantages of minimizing the number and amount of byproducts by using a complex reducing agent and producing an organic-transition metal hydride safely without denaturation under more moderate reaction conditions.
