Abstract

Simultaneous detection of NO concentration and temperature by a single sensor element was investigated. Resistance of the mixed oxide of 20SrSnO₃-80Fe₂O₃ was independent of gas, but decreased linearly with increasing temperature. However, capacitance of 20SrSnO₃-80Fe₂O₃ decreased with increasing NO concentration, although it was hardly changed upon exposure to CO and CH₄ and not significantly changed by CO₂ and H₂O. Therefore, NO concentration and operating temperature of sensors can be estimated simultaneously by monitoring the capacitance and the resistance of the 20SrSnO₃-80Fe₂O₃ mixed oxide. It is expected that the sensitive detection of NO can be achieved by the simultaneous detection of NO and temperature using 20SrSnO₃-80Fe₂O₃, since capacitance was strongly affected by temperature.
