Several zeolites of varying topology and with different Cu/Al ratios were investigated in the catalytic decomposition of NO, N 2 O and the NO-assisted N 2 O decomposition. The highest activity in the direct NO and N 2 O decomposition was found for bis(μ-oxo)dicopper cores in Cu-ZSM-5 followed by the EPR silent Cu in MOR, FER and BEA, while almost no activity was observed over...
The role of the bis(μ-oxo)dicopper core, i.e., [Cu 2 (μ-O) 2 ] 2+ , in the decomposition of NO and N 2 O by the Cu-ZSM-5 zeolite has been studied with combined operando UV–vis monitoring of the catalyst and on-line GC analysis. An optical fiber was mounted on the outer surface of the quartz wall of the plug-flow reactor and collected the UV–vis diffuse reflectance spectra...
