Abstract
The invention discloses a preparation method of multi-light metal coordination aluminum hydride hydrogen storage material, NaxLi(3-x)AlH6, wherein x is more than or equal to 0 and less than 3. The method comprises the following steps of: mixing NaH, LiH and simple substance Al powder, adding a small amount of Ti, Zr, V, Sc or rear earth-based catalysts, and carrying out mechanic grinding for 60 to 140h at the atmosphere of hydrogen so as to synthetize NaxLi(3-x)AlH6 (x is more than or equal to 0 and less than 3) multi-light metal coordination aluminum hydride. The method has the advantages of being capable of synthetizing the final product of NaxLi(3-x)AlH6 (x is more than or equal to 0 and less than 3) directly at room temperature by ball grinding, and having simple operation, low energy consumption and safety and reliability; in addition, the synthetized material has high yield, and high reversible hydriding and dehydriding capacity at medium and low temperature, thus being a novel hydrogen storage material with infinite commercial value.
