Adsorption properties of membrane catalysts

A method for adsorption measurements on catalysts with small surface areas has been devised. The adsorption of argon has been examined on membrane catalysts made from Pd-Ni and Pd-Ru alloys before and after catalytic experiments. A sharp change of the adsorption properties and an increase in the surface areas of catalysts after reactions have been observed. © 1977 Akadémiai Kiadó

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
