We use Electron paramagnetic resonance (EPR), ideally suited for investigating Cu2+ exchanged zeolites, to study hydrated Cu-SSZ-13 catalysts at various Cu loadings to gain insights into their locations. Also, NH3-SCR and NH3 oxidation kinetics are investigated over these catalysts at high space velocity conditions for the development of structure-activity relationships.
