Electrode kinetic study of silver-ion doping effect in solid-electrolyte potentiometric carbon dioxide gas sensor
Abstract
A kinetic study of Ag electrodes on Na{sub 2}CO{sub 3}/BaCO{sub 3} solid electrolyte using pressure modulation and electrochemical impedance spectroscopy reveals that the response to CO{sub 2}/O{sub 2} partial pressure changes is determined by a combination of a reaction process and subsequent diffusion of Ag{sup +} ions into the carbonate. This Ag{sup +} ion doping is assumed to enhance CO{sub 2} exchange kinetics at the carbonate/electrode interface and to be responsible for the observed improved CO{sub 2} gas-sensing performance.
