Abstract
The article describes the application of commercial manufacturing methods to the development of NOx/NH3 sensors for vehicle on-board emissions control. Implementation of devices that respond to NOx/NH3 in real-time with improved sensitivity, selectivity and response time over conventional mixed potential gas sensors is discussed. Leveraging LANL's (Los Alamos National Laboratory) unique mixed potential sensor design, a cost-effective and mass manufacturable prototype gas sensing platform has been developed. Experimental results from these engineered devices indicate the possibility of a combined NOx/NH3 sensor platform. Moreover, the challenges and limitations towards the commercialization of mixed potential NOx/NH3 sensors are summarized.
