Abstract: A series of Pd/Al2O3catalysts with different palladium loading was prepared by incipient wetness impreg-nation method. As it was shown by various physicochemical methods, palladium at concentrations notexceeding 0.5 wt.% favors to stabilize in an atomic dispersed ionic state. Appearance of PdO phase hasbeen firmly detected by TPR, DR UV–vis and EXAFS starting from Pd concentration of 1 wt.%. It was foundthat low-content Pd/Al2O3catalysts are characterized by high activity in CO oxidation due to atomicallydispersed palladium species tailored to the donor sites of the support. The presence of chemisorbed waterallows one to stabilize Pd in highly disperse state thus preventing the catalyst deactivation.
