Gas sensors are useful for the carbon dioxide concentration monitoring in many applications. The major challenge is to develop a potentiometric sensor working without the necessity of a reference gas and without a need of the reference electrode encapsulation. Important issue is a selection of reference electrode material, which should provide stable reference potential. For example as reference electrode material in sensor based on sodium conductive electrolytes Na2Ti6O12/TiO2, Na2Ti6O13/Na2Ti3O7, Na2SnO3/SnO2, Bi2Cu0.1V0.9O5.35 were used. One of the newest approach is usage of the oxide ion conductor Bi8Nb2O17/Pt reference electrode. In this work properties of several CO2 sensors based on Nasicon with Bi8Nb2O17/Pt as a reference electrode are investigated. The sensors differ from each other by techniques of a reference and sensing electrodes preparation.
