AMT An improved lowpower measurement of ambient NO2 and ...

Abstract. Lowcost sensors (LCSs) are an appealing solution to the problem of spatial resolution in air quality measurement, but they currently do not have the same analytical performance as regulatory reference methods. Individual sensors can be susceptible to analytical crossinterferences; have random signal variability; and experience drift over short, medium and long timescales.

Chemosensors | Free FullText | Enhanced NO2Sensing ...

NO2sensing properties of semiconductor gas sensors using porous In2O3 powders loaded with and without wt% Au (Au/In2O3 and In2O3 sensors, respectively) were examined in wet air (70% relative humidity at 25 °C). In addition, the effects of Au loading on the increased NO2 response were discussed on the basis of NO2 adsorption/desorption properties on the oxide surface.

· Most studies have been focused on sensing applications of WO3 for the detection of NO2 and a sensing mechanism has been established. However, less is known about NO sensing routes. There is disagreement on whether NO is detected as an oxidizing or reducing gas, due to the ambivalent redox behavior of nitric oxide. In this work, nanocrystalline WO3 with different particle size was …
