Abstract: The invention provides a method of producing a metal oxyhydride, capable of synthesizing the metal oxyhydride under reaction conditions close to atmospheric pressure, and excellent in productivity and cost. The method of producing a metal oxyhydride of the present invention includes reacting an oxide with a metal hydride in a hydrogen atmosphere. A non-oxygen element constituting the oxide comprises only one kind of non-oxygen element. A pressure condition of the reaction is 0.1 to 0.9 MPa, and a temperature of the reaction is 500 to 1000° C.

Abstract: The invention is related to a layered double hydroxide electride which can be produced without high-temperature treatment, and a production method of which cost can be reduced. The layered double hydroxide electride contains electrons between layers and has an electron density of 2.0×1018 cm−3 or more. The method of producing the layered double hydroxide electride includes a step of mixing a starting layered double hydroxide with an electron exchanger for exchanging anions existing between layers of the starting layered double hydroxide for electrons to produce the layered double hydroxide electride.
