NO2 and CO2 Sensing Properties of LISICON-Based Sensor Operative at Room Temperature [PDF]

Keywords: NO2 sensor, CO2 sensor, LISICON, NASICON, indium tin oxide (ITO)

NASICON) disks with sensing electrode materials, such as Au, indium tin oxide (ITO), and auxiliary phase (nitrate or carbonate). Their NO2 and CO2 sensing properties were examined under 30% relative humidity (RH) in the temperature range of 30 to 100℃. When the NO2 sensor was operated in the range of 2 to 7 ppm NO2 at 30℃, the LISICON sensor attached with ITO-NaNO2 had the highest sensitivity to NO2 and the electromotive force (EMF) change was 41.4 mV. At 30℃ under 30% RH, the EMF values of the LISICON sensor attached with ITO-NaNO2 were proportional to the logarithm of NO2 concentration. Also, when the CO2 sensor was operated in the range of 250 to 2,500 ppm CO2 at 30℃, the LISICON sensor attached with ITO-Li2CO3-BaCO3 had the highest sensitivity to CO2 and the EMF change was 20.0 mV. At 30℃ under 30% RH, the EMF values of the LISICON sensor attached with ITO-Li2CO3-BaCO3 were correlated linearly with the logarithm of CO2 concentration. Subsequently, to examine gas selectivity, the NO2 selectivity of the sensor attached with ITO-NaNO2 and the CO2 selectivity of the sensor attached with ITO-Li2CO3-BaCO3 were evaluated at 30℃ under 30% RH. As a result, it was found that the LISICON and NASICON sensors attached with ITO-NaNO2 were fluctuated by the change in CO2 concentration. On the other hand, although the NASICON sensor attached with ITO-Li22CO3-BaCO3 was affected by the NO2 concentration change, the LISICON sensor attached with ITO-Li2CO3-BaCO3 showed a high CO2 selectivity. From thermodynamic calculations, it was considered that the chemical instability of NASICON and NaNO2 under CO2 led to the degradation of NO2 gas selectivity in the ITO-NaNO2-attached sensor, whereas that of NASICON under NO2 caused the degradation of CO2 gas selectivity in the ITO-Li2CO3-BaCO3-attached sensor.
