Abstract :

This paper reports the synthesis, characterization and LPG sensing properties of Fe doped nano–sized tin oxide. The Fe doped nano–sized SnO2 powder was synthesized by using a chemical co–precipitation method using stannic chloride (SnCl4, 5H2O), iron chloride (FeCl3) and ammonium hydroxide (NH4OH), as starting materials and water as a carrier. The resulting nano–sized powder was characterized by X–ray diffraction (XRD) measurements, transmission electron microscopy (TEM) and thermogravimetric analysis (TGA). The LPG sensing properties of the synthesized Fe doped nano–sized SnO2 powder were investigated at different operating temperatures and LPG concentrations. It was observed that doping of Fe significantly enhances the sensitivity of the nano–sized SnO2 to the LPG. The sensitivity of Fe doped nano–sized SnO2 to 75 ppm of LPG is maximum at an operating temperature 350 oC and it was found to be ~ 504.30 %. The response and recovery times were found to be nearly 3 sec and 5 sec, respectively. Finally, the plausible mechanism for the enhancement in the LPG sensing properties was discussed.
