Abstract:
An improved NO x sensor with an NH 3 oxidation catalyst. A sensor module may include a support component, a NO x sensing material positioned on the support component, and an NH 3 oxidation catalyst. The NH 3 oxidation catalyst may be layered on top of the NO x sensing material or the NH 3 oxidation catalyst may be positioned upstream of the NO x sensing material such that the NH 3 oxidation catalyst selectively converts NH 3 to N 2 while permitting NO x through to the NO x sensing material.
