Abstract

SnO2nanorods with rutile structure were successfully synthesized by solid state reaction in the presence of NaCl-KCl. Indirect-heating sensors based on nanorods were fabricated and investigated for the gas sensing properties to ethanol. The results showed that the response of sensor to 1000 ppm ethanol is up to 114.3, the export voltage to 1 ppm ethanol can attain 2.0 V at 275 °C, and the response time and recovery time are no longer than 10 s.
