Abstract

The invention provides a hydrogen-producing material for hydrogen-rich water, which is made by grinding raw materials including the following mass percentages: Al 60-97.5wt%, Ga 0.5-10wt%, In 0.5-10wt%, Sr 0.5-10wt%, Bi2O3 1.0-10wt%. The present invention also provides a method for preparing hydrogen-producing materials for hydrogen-rich water. During the grinding process, defects formed between components and the presence of intermetallic compounds destroy the dense oxides on the aluminum surface, and Bi2O3 reacts with metal aluminum to generate Bi , Destroy the oxide film on the surface of metal aluminum, which is conducive to the continuous progress of the hydrolysis hydrogen production reaction, and improves the durability of the hydrogen production material in the process of producing hydrogen. The hydrogen-producing material for hydrogen-rich water provided by the present invention has strong controllability in the hydrogen production process, and there will be no accumulation of relatively high-concentration hydrogen gas; 1g of hydrogen-producing material can realize continuous hydrogen production for 1 to 2 minutes to stabilize hydrogen production and stable hydrogen supply .

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...
