| Research Abstract |
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.
