Abstract
A compact rod-type yttria-stabilized zirconia (YSZ)-based sensor utilizing In2O3 (+0.3wt.% Pt and 10wt.% YSZ) sensing electrode (SE) was fabricated with aspirations of monitoring ppb levels of propene (C3H6) in atmospheric environments. The developed YSZ-based sensor demonstrated good sensitivity and selectivity towards 50ppb C3H6 even under humid conditions (relative humidity: RH⋍32%). The C3H6 sensitivity as well as response/recovery rates of the developed sensor were relatively stable during the ten days of sensor operation. This stabilization was achieved via the application of intermediate YSZ layers between the electrodes and the underlying YSZ rod. The developed sensor exhibited excellent C3H6 sensing behavior; good quantitative determination of C3H6 concentration in the range of 20–600ppb; unaffected sensing performance towards 50ppb C3H6 even in the presence of interfering co-existing gases such as H2, CO, NO2, CH4, C3H8 and n-C4H10. During the final evaluation of the developed sensor, it was equipped with a low power consumption heater and employed for real time monitoring of C3H6 concentrations in real atmospheric environment. The developed sensor demonstrated comparatively similar trends of output signal (sensing signal) compared with that of a commercial hydrocarbon analyzer.
