| Outline of Final Research Achievements |
With the growing interest in recent environmental problems, monitoring and purification technology of nitrogen oxides released into the atmosphere from diesel engines has been attracting attention. In this study, we focus on electrolysis phenomena that leads to detoxification of the nitrogen oxides. Ionic conducting ceramics were applied for the electrochemical reduction of nitrogen oxides. As a result, nitrogen oxides were reduced to harmless nitrogen by active species generated by electrolysis of water. Because the electrochemical reaction occur in the both electrodes, alternate current will become applicable instead of direct current. Simultaneous reduction of nitrogen oxides at both electrodes suggests the simplification and downsizing of the devices for sensing and purification of nitrogen oxides.
