Low temperature high sensor response nano gas sensor using ITO nanofibers

Indium Tin Oxide (ITO) nanofibers were fabricated by the electrospinning process. Sensors based on these nanofibers were fabricated by applying silver paste as electrode. The morphology and crystal structure of ITO nanofibers were studied by Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD), respectively. The optimal working temperature and sensor response of ITO nanofiber sensors were investigated. All results showed that ITO nanofiber sensors have good sensor response for NO2 at temperatures as low as 50 °C.
