Metal sulfides for gas sensing applications ... - TU Delft Repositories

Accordingly, the SnOx/SnS is also used for detecting NO2 gas, which exhibits a high response of 161% towards 1 ppb NO2, wide detecting range (from 1 ppb to 1 ppm), an ultra-low theoretical LOD of 5 ppt, and excellent repeatability. To the best of my knowledge, such a LOD is the lowest among metal sulfide-based and metal oxide-based gas sensors. The sensor also shows excellent gas selectivity to NO2 …
