Abstract
Electrochemical oxidation of freshly deposited Pd and its alloys with other noble metals (Au, Pt, Rh) was compared with the behavior of samples subjected to prior hydrogen absorption/desorption procedure. It was found that surface oxidation of hydrogen-treated Pd and Pd–Pt–Au deposits starts at lower potentials than on non-hydrided electrodes and is accompanied by a negative shift of surface oxide reduction peak. Pd and its alloys with Au, Pt and Rh after hydrogen treatment are also more resistant to electrochemical dissolution than freshly deposited samples.
