Probing Pd-Co alloy particles supported on SiO2 by a variety of techniques (H2 and CO chemisorption, temperature programmed reduction (TPR), reactions of various alkanes, and x-ray diffraction) shows that the employed preparation and pretreatment result in the formation of fully reduced Pd-Co alloys characterized by good dispersion and lateral homogeneity. The surface enrichment in palladium is evidenced.
