To gain insight into the underlying mechanisms of catalyst durability for the selective catalytic reduction (SCR) of NO<sub>x</sub> with an ammonia reductant, we employed scanning transmission X-ray microscopy (STXM) to study Cu-exchanged zeolites with the CHA and MFI framework structures before and after simulated 135 000-mile aging. X-ray absorption near-edge structure (XANES) measurements were performed at the Al K- and Cu L-edges. The local environment of framework Al, the oxidation state of ...[more]
