| Outline of Final Research Achievements |
The synthesized iron oxyhydroxide has showed a high hydrogen generating ability as compared with the commercially available reagent. When the pH of the aqueous solution was low, it showed high hydrogen-producing activity. In addition, it was found that the amount of oxygen decreased with the generation of hydrogen, and there was a tendency for the hydrogen generation capacity to decrease under anoxic conditions. It was considered that iron oxyhydroxide produced a low valence iron ion by photo-self-reduction, which contributed to hydrogen production. Examination of other oxyhydroxides revealed that hydrogen is also produced in nickel oxyhydroxide and aluminum oxyhydroxide.
