| Outline of Final Research Achievements |
In this study, the relationship between the state of metallic complexes in the aqueous phase and its reduction potentials was evaluated through the homogenization of metal complexes in aqueous phase by using calculation.
Results of calculation for the every system indicated that Cu- and In- complex was successfully restricted to single species, and its reduction potentials were analyzed by using cyclic voltammetry. Synthesized materials were analyzed by XRD etc. These results clearly indicated that reduction potential and stability constants (Log K) showed linearly correlation. Therefore, it can be said that CuIn alloy nano particles can be synthesized by using aspartic acid as complex reagent and NaBH4 as reducing reagent.
