摘要：

Solid-state electrochemical sensors for volatile organic compounds (VOCs) based on commercial yttria stabilized zirconia (YSZ) sheet were fabricated using Pt or Pt covered with SmFeO3 layers as electrodes. The sensing performances were strongly influenced by the surface morphology of YSZ. The overcoat with SmFeO3 layer on the one side electrode enhanced the sensitivity for some VOCs. Even for 0.5 ppm of methyl ethyl ketone, ethanol and acetic acid, the changes of the electromotive force (EMF) in the levels of 20 mV and higher were confirmed at 400 degrees C for the monolithic type sensor in which one side electrode was over-coated with SmFeO3 powders.
