Research plan was founded on the basic research to develop techniques to synthesize highly crystalline nanomaterials for energy and environmental related applications. We synthesized highly pure copper oxides（CuO、Cu2O）nanoparticles for photoelectric conversion and confirmed their semi-conductor properties. We also constructed Cu2O:C60solar cells and evaluated their photo efficiency. We also developed techniques to synthesize Fe-Pt and Ni-Pt nanoparticles as catalytic electrodes for fuel cells. We demonstrated that Fe-Pt nanoparticles with fct crystalline structure on activated carbon could be used as an alternative candidate for Pt in PEFCs. Furthermore, Ni95Pt5and Ni90Pt10performed comparably with Pt particles in hydrogenation reaction, in spite of low Pt concentration. Finally, we also developed techniques to synthesize Fe-Co and Fe-Ni particles as electromagnetic wave absorbers and antenna material, respectively, and measured their high frequency properties. Fe-Co exhibited particle size dependent resonance peak in the range of a few GHz. On the other hand, Fe?Ni alloy nanoparticles, synthesized by hydrazine assisted polyol process, exhibited shape dependent low magnetic lossinthe MHz region.

研究计划建立在开发用于能源和环境相关应用的高结晶纳米材料合成技术的基础上，我们合成了用于光电转换的高纯度氧化铜（CuO，Cu2O）纳米颗粒，并证实了它们的半导体特性。 ：C60 太阳能电池并评估了其光效率。我们还开发了合成 Fe-Pt 和 Ni-Pt 纳米颗粒作为燃料电池催化电极的技术。活性炭上具有 fct 晶体结构的纳米颗粒可以用作 PEFC 中 Pt 的替代候选物。此外，尽管 Pt 浓度较低，但 Ni95Pt5 和 Ni90Pt10 在氢化反应中的表现与 Pt 颗粒相当。和 Fe-Ni 颗粒分别作为电磁波吸收剂和天线材料，并测量了它们的高频特性，在 范围内显示出与尺寸相关的共振峰。另一方面，通过肼辅助多元醇工艺合成的 Fe?Ni 合金纳米粒子，在 MHz 范围内表现出形状依赖的低磁损耗。
