An infrared study of CO adsorption on magnesia-supported ruthenium, gold, and bimetallic ruthenium-gold clusters provided evidence for metal-support interaction in the single-metal catalysts and for metal-metal interaction in the bimetallic catalysts which indicated that all the metal present existed as bimetallic clusters and that gold did not form separate clusters or segregate at the surface. The IR study was made at various degrees of coverage with CO of catalysts containing 2.1-4.7% metal (0, 11, 36, 90, and 100Vertical Bar3< gold) on magnesia and pretreated in hydrogen, helium or oxygen, and a comparison sample of 5% ruthenium on silica.
