(57) [Summary] (Modified) [Purpose] Treatment capable of obtaining a hydrogen storage metal material having a surface highly active for hydrogen molecules and a surface inactive for substances having surface poisoning other than hydrogen molecules Provide the law. [Structure] A hydrogen storage metal material, a high-concentration hydrofluoric acid solution or an anhydrous hydrofluoric acid solution, or a solution of an organic compound such as pyridine, triethylamine, or isopropyl alcohol and anhydrous hydrogen fluoride is placed in a reaction vessel, The reaction vessel is heated to a predetermined temperature from the outside, and in the heating process, a film containing a metal fluoride as a main component is formed on the surface of the hydrogen storage metal material to highly activate hydrogen molecules, and A method for highly activating and stabilizing a hydrogen storage metal material, which comprises deactivating a material having surface poisoning. |
