- A method of catalytically reacting an At alloy with water and a method of reacting a mixture of magnesium and metal oxide with water have been proposed, but the materials are expensive or the hydrogen yield is low, making them impractical. It has some disadvantages that are not the point. A possible solution to this problem is to react an alkali metal or alkaline earth metal such as sodium or calylum with water. However, alkali metals such as sodium and potassium react rapidly with water at about room temperature and generate intense heat, resulting in a dangerous hydrogen explosion.

る。By adding at least one metal among lead and zinc, it is possible to control the amount of hydrogen per hour, etc., and at the same time, it is possible to stabilize the alkali metal. That is, according to the water-splitting material of the present invention, since sodium hydroxide and potassium hydroxide aqueous solutions are produced as by-products in the reaction between amalgam and water, hydrogen can be stabilized by reacting the metals with water without supplementing alkali from other sources. It can be generated by
