Abstract

The present invention claims a hydrogen production method, which includes the following steps: S1. Prepare a metal target from fine metal powder, and then put the metal target into water, S2. Use a pulsed laser to scan the metal target through water According to a certain speed, the metal powder on the surface of the metal target is stripped layer by layer into the water, and the activated and modified metal fine powder reacts with water to generate hydrogen gas. S3. Recover and purify the hydrogen gas. In order to prevent or destroy the oxide film formed on the metal surface, the activated modified metal powder in the present invention utilizes the replacement characteristics between certain active metals and adopts a certain processing technology to obtain an alloy that can promote the continuous reaction of metal aluminum and water , until the end of the complete reaction. Compared with the direct ablation of the metal surface by laser, the laser energy required by the metal alloy surface pressed by exfoliated alloy powder in the present invention is much smaller; and the risk of explosion of a large amount of fine powder is eliminated.
