NO2 Response of Solid Electrolyte Sensors Made Using ZnFe2O4 Electrode
Keyword(s):
ZnFe2O4 powders are synthesized by solid phase method and used to make sensing electrode. Electrochemical cells are prepared with an oxygen ionic conductor (Y2O3-stabilized ZrO2: YSZ) with a semiconducting oxide (ZnFe2O4) electrode. Pt is used as the counter electrode. The devices shows promising NO2 sensing performance at 450, 550 and 650oC.The electromotive force (EMF) value of the ZnFe2O4/YSZ/Pt sensor increases with the increasing of concentrations of NO2 in N2.
