CO + O2 and CO + NO Reactions over Pd/Al2O3 Catalysts
The kinetics of the CO + NO and CO + O2 reactions have been studied over several different Pd/Al2O3 powder catalysts covering a wide range of average Pd particle sizes. The structure-insensitive nature of the CO + O2 reaction over Pd has been exploited to determine the relative dispersions in several Pd/Al2O3 powder catalysts by measuring the rate of that reaction and normalizing against surfac...

متن کاملMethane combustion over Pd/ZrO2/SiC, Pd/CeO2/SiC, and Pd/Zr0.5Ce0.5O2/SiC catalysts
The performances of different promoters (CeO2, ZrO2 and Ce0.5Zr0.5O2 solid solution) modified Pd/SiC catalysts for methane combustion are studied. XRD and XPS results showed that Zr 4+ could be incorporated into the CeO2 lattice to form Zr0.5Ce0.5O2 solid solution. The catalytic activities of Pd/CeO2/SiC and Pd/ZrO2/SiC are lower than that of Pd/Zr0.5Ce0.5O2/SiC. The Pd/Zr0.5Ce0.5O2/SiC catalys...
متن کاملNO reduction by CH4 in the presence of excess O2 over Pd/sulfated zirconia catalysts
The selective catalytic reduction (SCR) of NO by methane in the presence of excess oxygen has been studied on a series of Pd catalysts supported on sulfated zirconia (SZ). This support is not as sensitive to structural damage by steaming as the acidic zeolites, such as H-ZSM-5 and H-Mor. In previous studies, it was shown that this type of acidic zeolites are able to stabilize Pd2+ ions and prom...
