Silver as Storage Compound for NOx at Low Temperatures
Journal article, 2014
High loaded silver/alumina (16 wt%) was found to be suitable as a temporary NOx trap under cold start, so called passive NOx storage. High amounts of NOx can be stored in the presence of H-2 on this material below 200 degrees C and released below 400 degrees C under lean conditions or under rich conditions at adsorption temperature.
