| Research Abstract |
Improvements of sensing electrode of an amperometric-type zirconia-based NOx sensor were examined. As a result of investigation for making a thin-dense sensing electrode in order to enhance the NOx response, dense and thin electrodes of La0.8Sr0.2MnO3 on zirconia substrate were obtained by spin coating technique using 2-methoxyethanol solution containing La(NO3)3, Sr(OC3H7)2, Mn(CH3COO)2.4H2O mixed with ethanolamine and acetoine. It was also found that substitution of Mn with Al in La0.8Sr0.2MnO3 improves the stability in high-temperature reduction atmosphere, and the sensor shows high stability and response by optimization of composition and preparation method of the sensor electrode.
