Hydrogen electrosorption in Ni-Pd alloys

Hydrogen absorption in Ni-Pd alloys has been investigated. The amount of ab sorbed hydrogen in alloys containing below 20 at.% of nickel is equal to th e amount of hydrogen sorbed in pure palladium. Hydrogen absorption occurs i n the range 0-40 at.% of nickel concentration. Cyclic voltammograms recorde d at Ni-Pd alloys have characteristic peaks which overlap with the response s due to processes occurring on the surface at Ni and Pd atoms. Also some o f the processes characteristic of the pure metals can be distinguished from the recorded voltammograms. (C) 1999 Elsevier Science S.A. All rights rese rved.
