| Outline of Final Research Achievements |
We prepared carbon nanotube (CNT) -attached Pt nanocluster catalysts by the attachment of a Pt complex precursor on a CNT surface, by the surface decoration with polypyrrole (PPy), and by the subsequent reductive treatment, in order to attain high stability to Pt nanocluster catalysts. It was possible to decorate the CNT surface with PPy without the complete decomposition of the Pt complex structure, and PPy was attached in the close proximity of Pt complex. Subsequent reductive treatment provided Pt nanoclusters with the average diameter of around 1.0 nm on the CNT surface, as characterized by TEM. It was found that the particle diameter distribution of the Pt nanocluster was narrow compared to that of a sample without PPy decoration. Stable catalytic performances for the amination reaction of amine and alcohol on the prepared Pt nanocluster catalysts were observed.
