| Outline of Final Research Achievements |
Rhodium-doped titanium oxide layer compounds was synthesized as a hydride ion conductor in which the surface and grain boundaries were involved. We investigated whether the hydride species adsorbed on the rhodium-doped site exhibited surface hydride conduction. The conduction characteristics were evaluated in hydrogen or deuterium. The current-voltage characteristics and impedance characteristics changed when the H2 gas was changed to D2 gas, indicating that the ionic species involved in hydrogen are conducting. However, the conductivity was higher in the atmosphere in deuterium, which has a heavier mass, compared to the atmosphere in H2. These results indicated that new hydride conduction different from the normal hydride conduction mechanism may occur in the rhodium-doped titanium oxide layered body.
