Embodiment 1
[0035] This embodiment provides a semi-solid metal-based hydrolysis hydrogen production material, the material is composed of components containing the following mass percentages: 83% of the metal matrix element, 17% of the active element, wherein the metal matrix element is aluminum, The active elements are metal elements Ga, In and Sn.
[0036] The above-mentioned semi-solid metal-based hydrolysis hydrogen production material can be prepared by the following method, and the specific steps are as follows:
[0037] Step 1): Metal matrix elements containing 83wt.% industrial pure aluminum and active elements Ga, In, Sn containing 17wt.% are melted and casted at 700°C to make alloy blanks.
[0038] Step 2): The alloy blank made in step 1) is subjected to semi-solid secondary remelting at 620°C to make slurry, and after cooling, an Al-15wt.%GaInSn semi-solid block hydrolysis hydrogen production material is obtained, and the material has a semi-solid Tissue, in the semi-solid tis...
Embodiment 2
[0043] This example provides a semi-solid metal-based hydrolysis hydrogen production material and its preparation method. Compared with Example 1, this example is different in that the metal matrix element is Mg25wt.%Al alloy, the melting temperature is 680°C, and the second The remelting temperature is 500°C.
[0044] Compared with Example 1, the amount of hydrogen produced is greatly reduced.
