Abstract

The oxidation of NO to NO₂ is an important reaction step for various steps in a diesel or lean burn gasoline engines after-treatment system. Additionally, NH₃ oxidation is a useful reaction to understand the side reaction of the selective catalyst reduction (SCR) as well as to remove of excess NH₃ after SCR activity. Here, we investigated three different types of acid form zeolites Chabazite (H-CHA), Beta (H-BEA), and Mordenite (H-MOR) catalysts' activities for NO oxidation and NH₃ oxidation. Reaction temperature effects on the catalytic performance were observed by increasing the reaction temperature from 100^oC to 450^oC in intervals of 50^oC. Out of these three zeolites the acid form CHA showed highest activity due to the small pore cavity, which enhances the stability for transition complex.
