Abstract
Hydrogen sulfide is a typical toxic, inflammable gas. The detection of H2S is crucial in the areas of oil, natural gas and so on. However, studies on H2S gas sensors at room temperature were seldom reported. In this study, Quartz crystal microbalance (QCM) sensors have been utilized, and PVP film were prepared on the QCM by airbrush method with different airbrush volume for H2S detection. The results showed that the PVP film with airbrush volume 0.2ml exhibited a better sensing response to H2S gas. Besides, sensitive characteristics parameters, i.e. selectivity, stability, linearity and sensitivity of prepared sensors were studied for comparison. The relative sensing mechanism associated with SEM pictures was studied as well.
