Problems solved by technology

The invention patent (a hydrogen-producing Al-based alloy composite material and its preparation and use method, CN 1013583108) uses aluminum-tin and other alloys and carbon nanomaterials to be composited at high temperature. This system has good hydrogen production efficiency in neutral aqueous solution. This method needs to add a large amount of dopant carbon and tin, which reduces the theoretical hydrogen production of aluminum-based alloys
The disadvantage of this method is that the hydrolysis product Ca(OH) of metallic calcium 2 Slightly soluble in water, resulting in a slow rate of aluminum hydrolysis
Aluminum-calcium alloys need to be further crushed, salt-doped, and then ball-milled, which reduces the practical application prospects of this method

Abstract

The invention relates to a preparation method of a magnesium-aluminum alloy hydrogen-production material. The magnesium-aluminum alloy hydrogen-production material is obtained through mechanical mixing of weak-acid salt, briquetting and high-temperature treatment with magnesium-aluminum metal powder or magnesium-aluminum metal alloy powder as a precursor; the molar ratio of magnesium to aluminum is 0.1-1, and the mass of weak-acid salt is 0.01-20wt% of the mass of magnesium-aluminum alloy; positive ions of the weak-acid salt are one of sodium, potassium, calcium, barium and strontium; negative ions of the weak-acid salt are one of bismuth acid radical, tin acid radical, ferrum acid radical, germanium acid radical, meta-aluminic acid radical and meta-zinc acid radical. The magnesium-aluminum alloy hydrogen-production material is hydrolyzed rapidly in water or neutral water solutions to generate hydrogen and has extremely good application prospects in the field of portable hydrogen production.

Description

technical field [0001] The invention belongs to the field of hydrogen production, and in particular relates to a preparation method of a magnesium-aluminum alloy hydrogen production material. Background technique [0002] Metal hydrogen production materials, such as magnesium, aluminum, zinc, etc., have the advantages of low price, mild hydrolysis conditions, and large hydrogen production, and are one of the choices for portable hydrogen sources. Conventional metal hydrolysis hydrogen production is usually carried out in acid or alkaline solution, which will bring potential harm to users and require corrosion resistance of equipment materials; this virtually limits the application and development of metal hydrogen production materials. [0003] Nowadays, many researchers add other metals such as bismuth, tin, nickel, etc. to form an alloy phase, which greatly improves the reactivity of metals such as magnesium and aluminum in neutral water and solutions. The invention paten...
