Abstract
SnO2 nanostructure has been studied for gas sensing element as a nitrogen dioxide (NO2) detection application. These SnO2 is prepared by two different methods i.e., chemical and green method. The prepared material film coated top of the interdigitated electrodes (IDEs) by drop drying method were prepared to determine the gas sensing characteristics for the development of an toxic NO2 gas sensor. The prepared materials were introduced to oxidizing NO2 gas at room temperature. The response of these SnO2 material increase resistance and recommends their behavior as n-type semiconductor. The green method SnO2 sensor showed good response, sensitivity, selectivity, stability and reproducibility at 250ºC operating temperature towards 50 ppm of NO2. Therefore the green synthesized material is feasible to development with bio method of eco-friendly and cost-effective new device can be better over the conventional chemical method.
