摘要：

A solid-state electrochemical CO2 sensor was obtained by combining a fluoride ion conductor (LaF3) with an auxiliary phase of a metal carbonate. The sensor response (EMF) was found to follow the Nernst's equation for a 2-electron reduction of CO2 in the range of 40 - 2000 ppm at 400 and 450-degrees-C. The 90% response times were as short as 10-20 s at 400-degrees-C. The sensing mechanism of this new type CO2 sensor was discussed.
