Passive SCR has shown promise in reducing NO_X emissions for lean burn engines. NH₃ production is essential to the implementation of passive SCR. The effects of hydrothermal aging on NH₃ production have been examined for three potential passive SCR catalysts and the results have been compared to fresh catalysts.
