Development of Glass Dispersed Electrolyte and Electrode for Solid State SO2 Gas Sensor

Ajay Lad

Journal Title:Journal of Chemical, Biological and physical sciences

Electrochemical SO2 gas sensor fabricated using Ag+-glass dispersed Ag2SO4as an electrolyte. A sensor was prepared by depositing a thin layer of ferroelectric dispersed composite as an auxiliary phase. Modified the working electrode improves the sensor response due to presence of large number triple point (gas, Pt, electrolyte interface). The sensor was found responding to various test gas concentrations, showing Nernstian behavior (two-electron reaction) in limited range of gas partial pressure.
