Реферат:
The effect of CeO2 preparation procedure on the electronic and structural states of the active com
ponent of Pd/CeO2 catalysts and their activity in the lowtemperature reaction of CO oxidation was studied. The following two nonequivalent states of palladium were detected in the catalysts having lowtemperature activity using XPS and IR spectroscopy: Pd0(Pdδ+) as the constituent of a palladiumreduced interaction phase and Pd2+ as the constituent of a palladiumoxidized interaction phase PdxCeO2 ⎯ δ. It was found that the procedure used for preparing a CeO2 support considerably affected the formation of these phases and quantitative ratios between them. It was demonstrated that the palladiumoxidized interaction phase was responsible for lowtemperature activity, whereas the palladiumreduced interaction phase was responsible for activity in the region of medium and high temperatures.
