Abstract

A solid-state amperometric CO₂ sensor was fabricated by combining a Li⁺-ion conductor (Li₂CO₃-Li₃PO₄-Al₂O₃) with a porous layer and a Li₂CO₃ auxiliary layer deposited on sensing and counter electrodes, respectively. The Li⁺-ion pumping current increased linearly with increasing CO₂ concentration ranging from 200 to 2000 ppm at 400 °C and the 90% response time was approximately 55 s. This sensor was able to reliably detect a small change in the CO₂ concentration.
