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 (CaAlOO) to obtain hydrogen-substituted mayenite (CaAlOH) and reacting the resultant hydrogen-substituted mayenite (CaAlOH) with water to produce hydrogen, and hydrogen is produced by substituting hydrogen for free oxygen in mayenite (CaAlOO) to obtain hydrogen-substituted mayenite (CaAlOH), irradiating the resultant hydrogen-substituted mayenite (CaAlOH) with ultraviolet rays to obtain conductive mayenite (CaAlOe), and reacting the resultant conductive mayenite (CaAlOe) with water to produce hydrogen.
