Highly sensitive so2 sensor for gis

Highly sensitive so2 sensor for gis

In fact, they are 2.75 times more sensitive compared with the untreated MWNTs. From Figure 5(a), the response time of MWNTs-based gas sensors to H 2 S has also been improved greatly after treatment. The sensitivity of untreated MWNTs to SO 2 is about 2.5%, whereas the modified MWNTs have become less sensitive to SO 2.
