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