According to a study from the United States, "Catalytic decomposition of nitric oxide (NO) over Pd/Al2O3 and Ag-Pd/Al2O3 has been Studied using the pulse transient response technique coupled with in situ infrared (JR) and mass spectrometry (MS) at 723-823 K. In the absence of H-2, pulsing NO over the Pd/Al2O3 catalyst produces adsorbed NO species (i.e., Pd+-NO, Pd-0-NO, and Pd-NO-) as well as gaseous, N-2, O-2, and N2O products. Transient responses of the N-2 and O-2 profiles show that the addition of Ag onto Pd/Al2O3 catalyst shifts the O-2 profile forward, increases oxygen formation and the oxidation resistance of Pd, but did not decrease the amount of retained oxygen ...
