Semiconducting, mesoporous, glassy SiOC shows potential as sensor material

By Eileen De Guire / August 30, 2013

Glassy SiOC sensors responded well to NO2 below 400°C. Above 400°C, sensitivity to NO2 disappears, and they become responsive to H2, but the concentration is much higher—5 ppm for NO2 compared to 2,000 ppm for H2.
