  • Patent number: 9457334
    Abstract: The present invention provides a hydrogen production process, which is capable of producing hydrogen, which is a clean source of energy, simply and conveniently without using conventionally-used ammonia, with an extremely high level of safety. In accordance with the present invention, hydrogen is produced by substituting hydrogen for free oxygen in mayenite (Ca24Al28O644+.2O2?) to obtain hydrogen-substituted mayenite (Ca24Al28O644+.4H?) and reacting the resultant hydrogen-substituted mayenite (Ca24Al28O644+.4H?) with water to produce hydrogen, and hydrogen is produced by substituting hydrogen for free oxygen in mayenite (Ca24Al28O644+.2O2?) to obtain hydrogen-substituted mayenite (Ca24Al28O644+.4H?), irradiating the resultant hydrogen-substituted mayenite (Ca24Al28O644+.4H?) with ultraviolet rays to obtain conductive mayenite (Ca24Al28O644+.4e?), and reacting the resultant conductive mayenite (Ca24Al28O644+.4e?) with water to produce hydrogen.
