Composite material for manufacturing hydrogen and preparation method thereof

Abstract

The invention discloses hydrogen making composite material and a preparation method thereof, and belongs to the technical field of the functional metal composite material and the new material preparation. The composite material is prepared by weighting, mixing, heating to fuse, slowly mixing to cool and solidifying forming molecular sieve, metallic aluminium, metallic zinc and aluminium gallium according to a certain compounding ratio. Hydrogen gas can be stably generated through contacting the composite material with water, applying to occasions required to use hydrogen gas. The hydrogen making composite material has steady performance and simple and reliable preparation method. The invention can effectively reduce the production cost of hydrogen, save energy and consumption, avoid the safety problems in a plurality of links of hydrogen production, transportation, and storage in the traditional process, reduce the basic infrastructure investments in the hydrogen energy production, selling and transportation, and enable the large-scale hydrogen energy popularization and application to be possible.
