| Abstract(in English) | Ammonia is expected for the energy source of next generation, because the domestic production is almost 1.2 million ton a year. A highly active ammonia oxidation (AO) catalysts at low temperature needs to be developed to use ammonia as a fuel for the direct ammonia fuel cells (DAmFCs). In this study, shell-core catalysts made from the Pt, Rh and Ir complexes were synthesized with the combination of microwave-polyol, ethanol reductive and improved Cu-UPD (underpotential deposition) methods, and the performance of AO was evaluated. The results showed that the catalytic activity of the Pt shell-Ir core with the thinnest shell for AO was the highest in the catalysts. And the catalytic activity for AO with Pt outer shell/Ir inner shell/Rh core catalysts was lower than that with the thinnest Pt shell/Ir core catalyst, suggesting that an electronic effect from Rh core reached to the Pt outer shell. |
