Influence of the nature and amount of the second component of binary-palladium alloys on their catalytic activity with respect to the dehydrogenation of cyclohexane

1. The catalytic activity of palladium and binary alloys of it with nickel, silver, platinum, and boron with respect to the dehydrogenation of cyclohexane was studied. 2. Increasing the platinum content in the alloys to 1.5% increases their catalytic activity, while increasing the silver content in the range from 20 to 50% reduces their catalytic activity. The alloy of palladium with 5% nickel is more active, while the alloy with 10% nickel is less active than palladium. The apparent activation energy of the dehydrogenation of cyclohexane on all the indicated alloys, with the exception of alloys of palladium with platinum, are close to the value for palladium. 3. The catalytic activity of the alloys of palladium with boron studied is low and unstable. © 1971 Consultants Bureau

Influence of a catalytic reaction on the surface composition and roughness factor of palladium-ruthenium alloys

Using X-ray photoelectron spectroscopy (XPS) and differential flow methods, the surface composition and surface area of Pd-Ru alloys have been examined before and after their use as catalysts. The increase in the catalytic activity of the alloys leads to the enrichment of their surface in ruthenium. It is concluded that the catalytic activity of these alloys is governed by the composition, structure and (to a lesser degree) the roughness of the surface. © 1978 Akadémiai Kiadó
