| Research Abstract |
A direct ethanol fuel cell in which cheap, nontoxic and carbon-neutral bioethanol is used as a fuel is a significant power source for realizing a safe and eco-friendly society. However it is hard to break the carbon-carbon bond in an ethanol molecule, and therefore the development of a new active cathode catalyst for complete ethanol oxidation reaction to carbon dioxide is urgent. In this study we clarified with a model electrode that the selective and catalytic complete ethanol oxidation reaction was realized by not simple mixing but the controlled atomic arrangement of platinum/rhodium/tin oxides where platinum and tin oxides were not neighboring. Moreover we succeeded in synthesis of a nanoparticle catalyst with the controlled atomic arrangement.
