The titanium substrates were bombarded with 1 ?1016 ~ 1 ?1018 Pd+/cm2 at an energy of 40 keV. The palladium-implanted electrodes were studied with respect to their electrocatalytic properties for the hydrogen and oxygen evolution reactions in 30% KOH solution Results showed that the implanted electrodes were much more active than the untreated ones and had an increase in electrocatalytic activity with increasing implantation dose. The relative kinetic parameters were obtained by polarization measurements. These values showed that the titanium electrode implanted with high dose of palladium ions was similar to palladium electrode in these electrochem. properties. The surface compns. of implanted electrodes were discussed based on AES and XPS data.
