Embodiment 1

[0065] (1) Put 100g of aluminum in a graphite crucible and melt it at 850°C. After melting, stir the molten aluminum to remove the residue on the surface of the molten aluminum, then add 0.5g of tin, 0.1g of bismuth, 0.2g of zinc, and 0.5g of magnesium, Calcium powder 0.1g. The time interval between the addition of each metal is 1min, and the stirring is continued in the middle. Among them, the above-mentioned added metal elements are all low-melting point alloys. In order to prevent measurement errors due to high temperature volatilization at the moment of adding the alloy, aluminum foil is used to wrap the added metal in the experiment, and graphite stirring rods are used when adding. Press the aluminum foil into the molten aluminum, stir clockwise after about 5 seconds, stir for 5 minutes, then let it stand for 10 minutes, cast an ingot, let it cool naturally, demould, and press into tablets.

Abstract

The invention relates to an aluminum-based hydrogen production material, a preparation method thereof and a method for preparing hydrogen by splitting water. The aluminum-based hydrogen production material is prepared from the following components in parts by weight: 0.5 to 2.5 parts of tin, 0.1 to 1.5 parts of bismuth, 0.2 to 1.5 parts of zinc, 0.5 to 2.0 parts of magnesium, 0.1 to 0.3 part of calcium and 50 to 100 parts of aluminum. The aluminum-based hydrogen production material is prepared by adopting a melting method, a metal compound with lower cost is used for activating metal aluminum and preventing an oxidation film from being formed on the surface of the aluminum, the reaction characteristic of the metal aluminum and water is changed, the production cost of the hydrogen production material is greatly reduced, and the hydrogen production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to an aluminum-based hydrogen production material, a preparation method thereof and a method for producing hydrogen by splitting water. Background technique [0002] Hydrogen energy is a very good energy carrier, it does not emit any substances that pollute the environment, and it is a true green energy. However, the difficulty in the preparation and safe storage and transportation of hydrogen has become a bottleneck restricting the economic development of hydrogen energy. The real safe use of hydrogen energy should be real-time preparation and use, reducing intermediate storage and transportation. If the storage and transportation of high-energy compressed hydrogen can be transformed into the transportation of hydrogen production reactants, its safety performance will be greatly improved. [0003] In response to the above problems, many scholars have developed various...
