Abstract
A NOxstorage material comprises a support, a potassium salt impregnated on the support, the potassium impregnated on the support is promoted with a platinum group metal, and wherein the NOxstorage material has an electrical property which changes based on the amount of NOxloading on the NOxstorage material. An apparatus for direct NOxmeasurement includes a sensor coated with the NOxstorage material. A method of determining NOxflux in a NOxcontaining gas comprises exposing the gas to the apparatus and converting a signal developed by the apparatus to a signal representative of the NOxflux.
