Abstract

This research reports on the sensing behavior of a nanocomposite of tin dioxide (SnO2) and zinc oxide (ZnO). SnO2-ZnO nanocomposites were fabricated into sensor devices by the radio frequency sputtering method, and used for the characterization of the sensitivity behavior of methanol vapor. The sensor devices were subjected to methanol concentration of 200 ppm at operating temperatures of 150, 250 and 350 °C. A fractional difference model was used to normalize the sensor response, and determine the sensitivity of methanol on the sensor. Response analysis of the SnO2-ZnO sensors to the methanol was most sensitive at 350 °C, followed by 250 and 150 °C. Supported by the morphology (FE-SEM, AFM) analyses of the thin films, the sensitivity behavior confirmed that the nanoparticles of coupled SnO2 and ZnO nanocomposites can promote the charge transportation, and be used to fine-tune the sensitivity of methanol and sensor selectivity to a desired target gas.
