In this work a new and simple two electrode amperometric sensor for NO 2 detection is described. The sensor consists of a Nafion® proton exchange membrane (PEM), a Graphite working electrode, and a NiO counter electrode. The developed sensor presents a good sensitivity to NO2 and very small cross sensitivity to CO and O2. A dedicated measurement system was developed, and a measurement protocol was found, ensuring satisfactory performance also in terms of repeatability.

Abstract
In this work a new and simple two electrode amperometric sensor for NO 2 detection is described. The sensor consists of a Nafion® proton exchange membrane (PEM), a Graphite working electrode, and a NiO counter electrode. The developed sensor presents a good sensitivity to NO2 and very small cross sensitivity to CO and O2. A dedicated measurement system was developed, and a measurement protocol was found, ensuring satisfactory performance also in terms of repeatability.
