| Outline of Final Research Achievements |
We prepared metal nanowires by a radiation-reduction reaction occurring very locally in cylindrical heavy-ion tracks and then pursued the possibility of their applications to the oxygen reduction reaction catalyst in polymer electrolyte membrane fuel cells. According to the analysis of elemental chemical states and microscopic observations, the reduction of metal ions efficiently took place in each track, probably leading to the formation of metal nanowires whose morphology depended on the track structures.
