Abstract

The invention relates to a hydrogen storage material, in particular to a preparation method of a composite magnesium-aluminum-based hydrogen storage material. The preparation method comprises the following steps: cutting magnesium metal into magnesium blocks and taking the magnesium blocks as an anode and a carbon rod as a cathode to obtain deposited superfine magnesium powder; taking and grindinga manganese iron ore, rice husks and titanium powder and sieving to obtain mixed powder; melting an aluminum ingot, doping zinc powder, then reducing the temperature, adding dispersed powder and polytetrafluoroethylene, introducing argon for refining and cooling to obtain composite metal resin; and finally performing melting extrusion on the composite metal resin to obtain the composite magnesium-aluminum-based hydrogen storage material. The preparation method of the composite magnesium-aluminum-based hydrogen storage material, provided by the invention, has the benefits that manganese can prevent re-crystallization of magnesium-aluminum alloy and improve the impact resistance and the pressure resistance of the magnesium-aluminum alloy; titanium deposits on the surfaces of ultrafine powder particles of magnesium and carbon powder to form a Mg-Ti-C composite hydrogen storage material, so that the oxidation stability of the hydrogen storage material is improved; a transition metal element has a catalytic effect on the hydrogenation of the magnesium, and the contact area of reaction between the magnesium and hydrogen is increased, so that the hydrogen release rate of the hydrogen storage material is improved, and the hydrogen release temperature is reduced.

Description

technical field [0001] The invention relates to a hydrogen storage material, in particular to a preparation method of a composite magnesium-aluminum-based hydrogen storage material. Background technique [0002] With social development and population growth, human demand for energy will increase. Fossil energy represented by coal, oil, and natural gas is the main energy source at present, but fossil energy is a non-renewable resource with limited reserves, and the extensive use of fossil energy has also caused more and more serious environmental pollution problems. Therefore, the pressure of sustainable development forces human beings to look for cleaner new energy sources. [0003] As a clean and efficient energy source, hydrogen energy occupies an important position in social production. However, hydrogen energy is not easy to store and is difficult to use on a large scale. The development of hydrogen storage materials is the key to solving the technical problems of hydro...
