Project Description

Extensive and diverse studies performed in the last two decades have explored the effects of different variables to improve the Selective catalytic reduction (SCR) for the abatement of NOx pollutants. Recently, Cu-exchanged SSZ-13 (Cu-SSZ-13) zeolite catalyst has been commercialized due to its efficient reduction of NOx and superior hydrothermal stability in light and heavy-duty diesel vehicles. Nevertheless, a fundamental understanding of this catalyst and the NH3-SCR reaction mechanism are still under debate. I perform kinetics and characterization studies to gain insight of the active sites on Cu-SSZ-13 and contribute to the understanding of NH3-SCR mechanism. Additionally, I study the hydrothermal stability of small pore zeolites, i.e. SSZ-13, SSZ-39, and RTH, and the effect of diesel engine environment to evaluate potential catalysts for the reduction of NOx using NH3-SCR
