Sensor de gas LEED MH-Z19D

Visible-light activated room temperature NO2 sensing of ...

Feb 15, 2020 · The photo-energy actived gas sensor was developed for the detection of NO 2 by using the SnS 2 nanosheets as the gas sensing material.. The gas sensor exhibits a high response and an excellent selectivity to 8 ppm NO 2 under the green light illumination at room temperature.. The intrinsic mechanism of the SnS 2 based sensor could be attributed to the photo-generated electron-hole pairs.
