Mixed potential type ethanol gas sensor using Yttria-Stabilized Zirconia(YSZ)as solid electrolyte and LaFeO3 as sensitive material was fabricated and characterized. LaFeO3 was prepared by a sol-gel method and characterized by XRD.YSZ substrate and sensitive electrode were characterized using field emission scanning electron microscope. The measurement results show that the presented sensor exhibits a high sensitivity(135 mV to 400×10-6 ethanol)and fast response time(14 s to 50×10-6 ethanol)at 350 ℃. The results also demonstrate good repeatability and selectivity of the fabricated sensor.
