The spatiotemporal features of the multifunctional monolithic lean hydrocarbon NO x trap (LHCNT), for eliminating NO x (x = 1 and 2) and ethylene (C2H4), are examined using spatially resolved mass spectrometry (SpaciMS), spanning the sequentially positioned passive NO x adsorber (PNA; Pd/SSZ-13), hy...
