| Abstract: | A H2 chemisorption and TPR study of Ru–Ag/SiO2 catalysts reveals that after oxidation at 373 K this systems behaves like Ru–Cu/SiO2. High temperature oxidation, however, does not result in the separation of the metal like in the Ru–Cu case but in the redispersion of Ag on top of the Ru particles.
