Abstract

See full text

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.
