“…Several sensors have been fabricated during the last decade to selectively detect various VOC components like ethanol, acetone, hydrocarbon, and LPG. Some of these SMO sensors contain single metal or mixed metal oxides like SnO 2 and SnO 2 -based materials [207-220], WO 3 and WO 3 -based materials [221-224], titanium based oxides [225-227], zinc based oxides [214,224,228], iron based oxides [229,230], cobalt based oxides [231], cerium oxide sensor [232], and copper based materials [233]. …”

“…27,28 We also showed that the BiCuVOx-based device with perovskite electrodes responded to gaseous mixtures of volatile organic compounds (VOCs) in ppm concentrations at 350-400 °C. 29,30 The lower operating temperature enabled us to detect combustible VOC gases more efficiently. The response to VOCs can be explained in terms of the mixed potential theory.…”

“…We have previously developed a planar mixed-potential-type BiCuVOx device for VOC detection in which sensing and counter electrodes made of the same materials but different thicknesses were exposed to a sample gas atmosphere. 30 The development of planar devices that do not require a reference gas is of interest for the miniaturization and manufacture of devices with thick-film technologies. However, the sensor response of this planar device was lower than that of a concentration cell with a reference gas.…”

Mixed-potential-type gas sensors are promising solid-state devices for the in-situ detection of ppm concentrations of air pollutants in the atmosphere. In this study, we designed electrode structures of mixed-potential-type sensors using a BiCuVOx (Bi 2 V 0.9 Cu 0.1 O 5.35 ) solid electrolyte to control the responses of electrodes to organic gases. Devices fitted with sensing and counter electrodes made of a composite of BiCuVOx and a perovskitetype oxide (La 0.6 Sr 0.4 Co 0.8 Fe 0.2 O 3 ) were fabricated and tested for their ethanol-sensing properties. Sensor devices with a three-electrode configuration, in which a reference electrode was exposed to a standard air mixture, were fabricated to separately measure the potentials of the sensing and counter electrodes relative to the reference electrode. When a thin (30 µm) sensing electrode and a thick (68 µm) counter electrode were attached to a planar device, the sensing electrode exhibited high responses to ethanol at 350 and 400 °C. However, the overall signal was still small because the counter electrode also responded to ethanol. In another planar device in which the counter electrode was coated with a Pt/Al 2 O 3 catalyst, the counter electrode exhibited almost no response to ethanol resulting in the generation of large sensor signals. This is because the catalyst layer efficiently decomposed ethanol and impeded its diffusion to the reaction interface between the counter electrode and the solid electrolyte. The device coated with the combustion catalyst also showed good response and recovery speeds and high stability under humid conditions indicating its feasibility as a practical, compact ethanol sensor.
