Outline of Final Research Achievements |
Gold nanofibers have been found to be formed via a spontaneous and heterogeneous electron-transfer reaction at the soft liquid/liquid interface between highly hydrophobic ionic liquid and water. The tips of the nanofibers show a dendritic structure. The dendrites are bundled to nanofibers except around the tips. Electrochemical reactions at the ionic liquid/water interface have revealed that electron transfer and ion transfer are coupled, leading to the spontaneous reductive deposition of the gold nanofibers. The several roles of the ionic liquid for the dendritic nanofiber formation have been found.
