    Abstract

    Sn2O3-based NO gas sensors were fabricated and investigated in this study. The sensor dopedby 1.0 at.% antimony had a maximal response to NO gas at 473K. The NO gas with a concentration down to 10 ppm can be detected by the sensor without any cross sensitivity to the interfering species such as NO2 and CO. The response speed was shortened about 5.7 times after mixing the 10.0 wt.% SnO2 nanoparticles into the 1.0 at.% Sn2O3:Sb gas sensor, which was resulted from the formation of Sn2O3–SnO2 hetero-junction.This kind of mixed-oxides gas sensor showed good response to NO gas, weak response to NO2 gas and unstable response to CO gas
