Abstract

The invention provides a hydrogen manufacturing material for hydrogen-enriched water. The hydrogen manufacturing material for hydrogen-enriched water is prepared by grinding the raw materials in percentages by mass: 60-97.5wt% of Al, 0.5-10wt% of Ga, 0.5-10wt% of In, 0.5-10wt% of Sr and 1.0-10wt% of Bi2O3. The invention further provides a preparation method for the hydrogen manufacturing material for hydrogen-enriched water. A compact oxide on the surface of aluminum is damaged as a result of defects formed among components in a grinding process and the presence of an intermetallic compound, and a thermit reaction is performed on Bi2O3 and metal aluminum to generate Bi which damages the oxide film on the surface of the metal aluminum, so that a hydrolytic hydrogen manufacturing reaction is favorably performed continuously, and the persistence of the hydrogen manufacturing material in a process of manufacturing hydrogen is improved. The hydrogen manufacturing material for hydrogen-enriched water provided by the invention is high in controllability of hydrogen manufacturing process, and hydrogen with relatively large concentration is not gathered; 1g of the hydrogen manufacturing material can stably supply hydrogen continuously for 1-2 minutes with stable hydrogen production.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production materials, and in particular relates to a hydrogen production material for hydrogen-rich water and a preparation method and application thereof. Background technique [0002] Water is an important part of human tissue. The content of water in the human body is as high as 70%. 60% of the water in the human body exists in cells, and 40% exists in fluids such as blood, digestive juice, and saliva. Medical research shows that many diseases, including aging, are caused by the accumulation of free radicals in the body that cannot be removed in time. Oxygen entering the body is transported to each cell through the red blood cells in the blood, and sugar and fat are burned and consumed in order to generate energy in each cell. Among them, 2% of the oxygen will become active oxygen, so a large amount of active oxygen will be produced in the human body. The peroxidative lethality of oxygen fre...
