  • Solid-state electrochemical sensor devices combined with a sodium ion conductor (Na5DySi4O12) disc and metal-sulfide sensing electrodes synthesized via solution routes have been investigated for the detection of SO2 in the range 20–200 ppm at 150–400°C. Among the various sulfide sensing electrodes tested, the metal-mono sulfide-based electrodes (NiS, CdS, SnS and PbS) gave good SO2 sensitivity at 300–400°C. The CdS-based solid electrolyte sensor element showed the best sensing characteristics… CONTINUE READING
