Electrode Kinetic Study of Silver-Ion Doping Effect in Solid-Electrolyte Potentiometric Carbon Dioxide Gas Sensor.
-Studies of Al electrodes on Ag+-doped Na2CO3/BaCO3 solid electrolyte, performed by a combination of electrochemical impedance and pressure modulation spectroscopies, show that the response to CO2/O2 partial pressure changes is due to a combination of a reaction process and subsequent diffusion of Ag+ ions into the carbonate. The observed improvement of gas sensing performance is attributed to an enhancement of CO2 exchange kinetics at the carbonate/electrode interface caused by Ag+ doping. -(DUBBE, A.; WIEMHOEFER, H. D.;
