Abstract
In this study, tungsten oxide (WO3) nanofibers were prepared using electrospinning technology and combined with La0.8Pb0.2FeO3 (LPFO) perovskite materials to form a heterostructure film, and then used to evaluate the potential as a gas sensing material. The results show that the pure WO3 nanofiber gas sensor has an excellent sensing effect on nitrogen dioxide (NO2) and hydrogen sulfide (H2S), and the WO3/LPFO heterostructure film gas sensor still has a high response to H2S, but the response to NO2 is suppressed. This WO3/LPFO heterostructure film gas sensor greatly improves the gas selectivity, making the selectivity more specific. The WO3/LPFO heterostructure film gas sensor exhibits excellent gas selectivity for H2S gas, the optimal operating temperature is 175 °C, and the response is about 89.5% under 1.25 ppm H2S gas.
