摘要：
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.
