Nitromethane Sensing Characteristics of SnO2 Gas Sensors and Infrared Spectroscopic Study
E-mail:
The SnO2-based thick film sensors were fabricated by screen printing and dipping methods, and their sensing characteristics to CH3NO2 gas were investigated. The oxidation products of CH3NO2 on the thick film were analyzed by FT-IR using a heatable gas cell. The IR results showed that the products formed by oxidation of CH3NO2 at 300 ℃ on the SnO2/Al2O3/Pd thick film were mainly CO2 and NH3, while on the SnO2/Al2O3/Nb2O5/SiO2 thick film products such as CO2, H2O, N2O, and NH3 were observed. The thick film devices containing SiO2 showed high selectivity and negative sensitivity to CH3NO2 due to the presence of nitrogen compounds produced by oxidation of CH3NO2. Optimum amount of Nb2O5 and operating temperature were 1.0 wt% and 300 ℃, respectively.
