Abstract:
A sodium-ion conductor (Na 3 Zr 2 Si 2 PO 12 : NASICON)-based CO 2 sensor using a Li 2 CO 3 -BaCO 3 electrode responded very well to CO 2 in air over a wide temperature range of 270-600°C. The sensor responses, electromotive force (EMF), to varying partial pressure of CO 2 ( P CO 2 ) were in accordace with a 2-electron reaction of CO 2 . On the other hand, the sensor response to a fixed P CO 2 (2×10 -3 atm) was almost independent of partial pressure of O 2 ( P O 2 ) at temperatures above 450°C, while at 305°C and below, it depended on P O 2 in a manner similar to a 2-electron reactionof O 2 . Thus, two types of sensing electrode reactions were indicated to occur depending on working temperature.
