“…However, the ionic conductivity is low and equilibration time is rather long. For type III sensors, most sodium ion conducting electrolytes such as Na-β-alumina [3] and NASICON [4][5][6] were used in combination with a Na 2 CO 3 auxiliary phase or a mixture of Na 2 CO 3 and Ba 2 CO 3 . Lithium ion conducting electrolytes [7] such as LIPON [8] combined with a lithium carbonate auxiliary phase were also used in type III sensors.…”

“…There have been a number of works on electrochemical CO 2 sensors with type III potentiometric design for various combinations of solid electrolytes, and electrodes (sensing, reference) [1][2][3][4][7][8][9]. In the level of laboratory experiment, they showed satisfactory CO 2 sensing characteristics including fast response, high sensitivity, and excellent selectivity.…”

Practical small-sized thick film CO 2 sensor with self-heater was fabricated with Na β-Alumina (NBA), Na 2 Ti 6 O 13 -TiO 2 , and Na 2 CO 3 as a solid electrolyte, reference electrode, and a sensing electrode, respectively. The measured EMF from the sensor followed the Nernstian behavior with CO 2 concentration change in the range of 400 to 600 • C (350-580 mW power consumption). However, in the aspect of stability, densification of the NBA thick film and prevention of Na 2 CO 3 evaporation were needed. In this study, an Al 2 O 3 porous layer deposited on Na 2 CO 3 was effective in improving the durability during operation of the sensor. It is thought that Al 2 O 3 suppresses evaporation of Na 2 CO 3 .

To improve the stability of Na3Zr2Si2PO12 (NASICON)-based potentiometric CO2 sensors fitted with carbonate/Au layers (sensing electrode), mixed conducting oxides of Li0.4CoO2 and Na0.6CoO2 were examined for their applicability to solid-reference electrodes in terms of their stability against CO2 and humidity. Compared with the Na0.6CoO2 electrode, the Li0.4CoO2 electrode showed far better stability against CO2 . When the Li0.4CoO2 electrode was coated with a layer of glass, the electrode showed no response to CO2 (200–2000 ppm) and little interference from humidity [21–86% relative humidity (RH)] at 450°C . A CO2 sensor device using Li2CO3–BaCO3 and a glass-coated Li0.4CoO2 showed stable electromotive force (emf) responses to CO2 in humid air (86% RH) at 450°C . The emf of the device was also stable even after it was exposed to humid air (86% RH) containing CO2 (400 ppm) at room temperature for 1–2 days. The present study indicates the promising features of the glass-coated Li0.4CoO2 as a stable solid-reference material for NASICON-based CO2 sensors.
