Ammonia Oxidation Activity of Pt Alloy Thin Film Electrode in Alkaline Solution

Hydrogen production using renewable energy is regarded as a key technology to achieve sustainable society. But hydrogen has low volumetric density and it’s difficult storage transport. Therefore, ammonia normally produced by the Haber-Bosch process with nitrogen attracts much attention carrier. Although toxic, it risk because we can detect immediately due its characteristic smell when leaks. So, direct fuel cell (DAFC) that directly generates electricity from expected be new power generation system. Pt used an anode catalyst for oxidation reaction in DAFC, but alternative one required expensive deactivated adsorbed N species. In this study, focused on alloy anodes. We chose Al, Cu Ni alloying elements. have discovered improvement of activity other Especially, Pt-11.6at.%Al showed highest current, 7.33 mA cm-2, will attractive candidate DAFC.
