| Outline of Final Research Achievements |
By using the synthesis process of nanoparticles by vapor quenching (Plasma-gas-condensation method), we have studied (1) searching for novel fuel cell electrocatalysts using alloy nanoparticles, (2) research on exchange coupled magnets with soft / hard magnetic composite nanoparticles, (3) research on lithium battery negative electrode materials. The results of (1)are summarized below.
By elemental mapping of STEM, Ni and Pt are distributed more inside the particles in the prepared Ni-Zn-Pt alloy nanoparticles, and Zn is distributed more outside the particles. As for the Ni-Pt and Ni-Zn-Pt alloy nanoparticles, the maximum power density increases as the amount of Pt increases. In addition, the Ni-Zn-Pt alloy nanoparticles maintain high catalytic activity even on the low Pt composition side of about 10 at.% Pt as compared with the Ni-Pt alloy nanoparticles.
