    Abstract: An example method includes determining that a selective catalytic reduction (SCR) component having a zeolite-based catalyst is contaminated with platinum (Pt). The method further includes elevating the temperature of the SCR component to at least 600° C. in response to the determining the catalytic component is contaminated with Pt, and maintaining the elevated temperature of the catalytic component for a predetermined time period thereby restoring reduction activity of the catalyst.

    Abstract: A method includes providing a zeolite material including a plurality of active sites. The plurality of active sites are bound to a plurality of hydrogen ions. The method includes exchanging at least a portion of the plurality of hydrogen ions with a plurality of copper ions, thereby forming a first amount of Z2Cu active sites that include copper (Cu2+) ions bound to the zeolite material and a first amount of ZCuOH active sites bound to copper hydroxide ions bound to the zeolite material. The method includes heating the zeolite material to a heat treatment temperature for a predefined time period to transform the zeolite material into a heat treated zeolite material. The heat treated zeolite material includes a second amount of Z2Cu active sites greater than the first amount of Z2Cu active sites and a second amount of ZCuOH active sites less than the first amount of ZCuOH active sites.
