  • Abstract
    The authors report on the fabrication of H2S gas sensors made of SnO2 mixed with ZrO2. Their sensitivities, responses, and selectivities to H2S are presented. A 10-p.p.m. concentration of H2S gas changes the sensor resistivity to a value 300 times lower than that for air around 175°C. The sensors exhibit highly selective detection of H2 S in an atmosphere containing H2S and H2. The mechanism of the reaction between the sensors and H2S are also discussed
