PROBLEM TO BE SOLVED: To provide a multifunctional and low-cost higher alkali metal-transition metal oxide.SOLUTION: The inside of a stainless steel- or iron-made reaction cell 1 is filled with an oxygen-free atmosphere, an alkali metal-containing compound such as NaOH or KTiOis placed therein as a reactant, fine particles of the reactant are scattered therein by heating the reaction cell 1 to 500-700°C, a higher alkali metal-transition metal oxide film is generated on an inside wall of the reaction cell 1 by supplying steam to the reaction cell 1, and the oxide film is used as a moisture absorbent, a hydrogen storage material, an electrode material of a fuel cell, and a nuclear reaction inducer. |
