| Abstract: | Adsorption of hydrogen, oxygen and carbon monoxide on Pd–Ag/Al2O3 catalysts of different compositions within the temperature range from 293 to 773 K has been investigated. Adsorption measurements have been carried out by the pulse chromatographic method. The results obtained reflect interactions of the above adsorbates with the alloy surface, strongly enriched in silver atoms, as a result of surface segregation processes.
