| Outline of Final Research Achievements |
Various applications are expected for the noble-metal nanocrystals such as gold nanorod, gold spherical nanoparticles, and silver nanoparticles, because of their unique optical and catalytic properties. In order to reduce of the noble-metal materials however, development of recovery and reuse methods are required. In this work, it is demonstrated recovery of them using a long-chain amine derivative C16CA. The nano crystals were encapsulated in the C16CA lamellar-structured supramolecules due to the strong affinity of amine and carboxylate of C16CA. Recovered nano crystals were also redispersed by changing pH, and the optical and catalytic properties of them were remained along the recovery-redispersion procedure.
