Ammonia sensors based on metal oxide nanostructures

· medical practice as well as the automotive and chemical industries [1]. There have been reports on ammonia sensors, but they do not make use of nanostructures. Thus, thin films of ZnO and ZnO doped with different metals have been found to sense ammonia with sensitivities varying between 4 and 95 for 1–30 ppm of NH 3 over the temperaturerange 30–300 C[2, 3]. Surface-ruthenated ZnO …

NOx Sensors - DieselNet

Abstract: Automotive NOx sensors are primarily of the amperometric type, ... The ammonia sensor has also been introduced by Iveco on their Daily van and on some of their heavy-duty engines. A wider use of NH 3 sensors may still be seen in the future, if more stringent NOx emission standards are adopted, such as the (now voluntary) California NOx standard of g/bhp-hr. The Delphi ammonia ...

Development of a Selective Mixed-Potential Ammonia Sensor ...

In this study, highly selective ammonia sensors were developed to detect ammonia emissions from automotive exhaust. The sensors were fabricated with 8-YSZ electrolyte, a platinum reference electrode and a working electrode of Au-V 2 O 5 (mass ratio 85/15), screen-printed on an alumina substrate. A platinum resistor was printed at the backside of the support to control the sensor temperature ...
