  • 17/08/2020: The group of A.N. Volkov prepared a new article “Electrochemical sensors based on proton-conducting electrolytes for determination of concentration and diffusion coefficient of CO2 in inert gases”, which will be published in the journal Chemical Engineering ScienceTo analyze CO2 in gas mixtures, a sensor based on a proton-conducting electrolyte of the LaYO3 family was used. Such an electrolyte can transport protons from a humidified atmosphere to an atmosphere containing CO2, then reducing carbon dioxide. Under stationary conditions, the limiting current is formed, which forms the basis of temperature or concentration calibration dependences for subsequent analysis. This work expands the area of possible application of electrochemical devices based on proton-conducting electrolytes.
