Hydrogen production method

Abstract

The invention discloses a hydrogen production method. The method comprises the following steps: S1, preparing metal fine powder into a metal target material, and putting the material target material into water; S2, scanning the metal target material through water by adopting pulse laser, stripping metal powder on the surface of the metal target material into the water layer by layer at a certain speed, and reacting the activated and modified metal fine powder with the water to generate hydrogen, and S3, recovering and purifying the hydrogen. In order to prevent or destroy the formation of an oxide film on the metal surface, the activated and modified metal powder utilizes the replacement characteristics of some active metals and adopts a certain processing technique to obtain the alloy, and the alloy can promote the continuous reaction between the metal aluminum and water until the complete and sufficient reaction is finished. Compared with a method of directly ablating the metal surface by laser, the method has the advantages that the laser energy required by the metal alloy surface formed by pressing the stripping alloy powder is much smaller; and the risk of explosion of a largeamount of fine powder is eliminated.
