(247e) Assessing the NH3-SCR Redox Chemistry over Cu-CHA Catalysts Via the Synergy of Transient Kinetic Analysis and Computational Method

I will discuss the joint application of flow-reactor experiments (transient response methods, kinetic runs, probe reactions, chemical trapping), spectroscopy (UV-vis and XAS) and theory (DFT) to elucidate independently the two half cycles of the low-temperature NH3-SCR redox chemistry over Cu-CHA catalysts, and combine them to arrive at a kinetically and theoretically consistent closure of the redox cycle.
