Abstract
A solid electrolyte CO2 sensor using a sodium ionic conductor and a lithium carbonate-based auxiliary phase was investigated. The sensor responded excellently to CO2 in the temperature range of 350–600° C, without being affected by coexistent water vapor. The EMF responses to varying partial pressures of CO2 (P CO 2) followed a 2-electron reaction of CO2 under fixed P O 2. Under fixed P CO 2 (2×10−3 atm), the EMF was found to be almost independent of P O 2 at temperatures above 450° C, while it depended on P O 2 following a 2-electron reaction of O2 at 305° C and below. Two alternative sensing electrode reactions were proposed to take place depending on the working temperature.
