| Outline of Final Research Achievements |
Zn-Al layered double hydroxide (LDH) thin films intercalated with Eosin Y were prepared by the sol-gel method with hot water treatment. The heat-treated Zn-Al Eosin-Y LDH thin film was confirmed to work as the electrode of a solar cell under visible light irradiation. Powders of Zn-Al layered LDHs intercalated with eosin Y were also found to show the photocatalytic activity under visible light irradiation.
The ionic conductivity of (Ni, Mn)-Al LDHs and (Ni, Mn)-Fe LDHs intercalated with CO32- was found to be higher than that of Ni-Al LDH or Ni-Fe LDH. The addition of LDHs to the catalyst layer of an air-electrode increased the current for oxygen reduction reaction (ORR). H2-O2 fuel cells with Mg-Al LDHs as an electrolyte were confirmed to be operated.
