Title:
Hydrogen production method
Document Type and Number:
Japanese Patent JP6048933
Kind Code:
B2
Abstract:
The present invention provides a hydrogen production method that has very high safety and can easily product hydrogen, which provides clean energy. without using ammonia as has been conventional. By means of the present invention, it is possible to produce hydrogen by reacting water with a hydrogen-substituted mayenite ( Ca 24 Al 28 O 64 4+* 4H - ) resulting from substituting hydrogen for the free oxygen in mayenite (Ca 24 Al 28 O 64 4+* 2O 2- ), and it is possible to produce hydrogen by reacting water with conductive mayenite (Ca 24 Al 28 O 64 4+* 4e') obtained by means of ultraviolet irradiation of the hydrogen-substituted mayenite (Ca 24 Al 28 O 64 4+* 4H - ) resulting from substituting hydrogen for the free oxygen in mayenite (Ca 24 Al 28 O 64 4+* 2O 2- ).
