Problems solved by technology

However, the material has the following problems: when the bismuth content decreases, its hydrogen release performance also decreases, and when the bismuth content is lower than 5wt%, the formed alloy does not react with water, that is, no hydrogen is produced
However, there are problems with this material: the reaction in alkaline solution requires high corrosion resistance of equipment, and the current research hotspots mainly focus on the rapid reaction of aluminum and water under neutral conditions.

Abstract

Disclosed is a preparation method of an aluminum-base composite hydrogen production material processed through spark plasma sintering. According to the preparation method, after ball milling of Al powder, Bi powder and a carbon material is accomplished, SPS (spark plasma sintering) is conducted, and therefore a material is formed. The mass ratio of the Al powder to the Bi powder to the carbon material is 2.85:0.09:0.06, wherein the carbon material is one or more kinds of carbon nanotubes, graphene, oxidized graphene, activated carbon and graphite. The preparation method comprises the following steps that (1) the ball milling process is conducted, wherein the Al powder, the Bi powder and the carbon material are weighed and added to a ball milling jar, then milling balls are added, sealing is conducted, and then ball milling is conducted; and (2) the aluminum-base composite hydrogen production material which is uniformly mixed is taken out and placed into a graphite die, the graphite die is placed into an SPS cavity to conduct SPS, and the needed material is obtained. The preparation method has the following advantages that the preparation method is rapid, saves energy and protects the environment; the oxide film on the surface of the Al powder is broken through SPS, the Al-H2O reaction is promoted through SPS, and the hydrogen production performance of the reaction is improved; and the obtained material is high in oxidation resistance, so that the preparation method has the broad application prospect in the field of portable movable hydrogen sources.
