| Outline of Final Research Achievements |
This research aims to develop high-performance solid-state electrochemical gas sensors for monitoring automobile exhausts and air pollutants. We fabricated various kinds of gas sensors by using an yttria-stabilized zirconia (YSZ) as a solid electrolyte as well as various oxides (or metal nanoparticles) as sensing electrodes (SE) which were designed their microscopic structures, chemical compositions and crystal structures. As a result, novel high-performance electrochemical gas sensors were developed by controlling catalytic activities of electrochemical reactions at the SE/YSZ interface as well as gas-phase reactions in the SE layer.
