N2 - A series of Pd/Al2O3 catalysts with different palladium loading was prepared by incipient wetness impregnation method.

It was found that low-content Pd/Al2O3 catalysts are characterized by high activity in CO oxidation due to atomically dispersed palladium species tailored to the donor sites of the support.
