INFLUENCE OF MERCURY ADSORPTION ON HYDROGEN EVOLUTION AT PLATINUM AND PALLADIUM

Potentiodynamic I vs. E curves were recorded in order to investigate the influence of mercury adsorption on the activity of smooth Pt and Pd electrodes as well as Pd/Pd electrodes in the hydrogen evolution reaction. It was shown that both in acidic and in alkaline solutions the effect of Hg adatoms consists in an inhibition of the slow reaction step by the blocking of sites accessible to hydrogen adsorption

Electrochemical behavior of allyl alcohol, malenoid and fumaric acids on Pd/Pt and Pt/Pt electrodes

Electrochemical behavior of Pd-Pt and Pt/Pt electrodes in acidic water solutions of allyl alcohol, fumaric and malenoid acids has been studied. The results obtained at Pd/Pt and Pt/Pt electrodes were analyzed, and it was found that surface absorption ability of Pd/Pt electrode increases in the row fumaric acid-malenoid acid-allyl alcohol. Absorption activity of Pt/Pt electrode is higher than that of Pd/Pt one
