The electrochemical reduction of oxygen on thin Pd films with a nominal thickness of 0.25-10 nm on polycrystalline Au substrate (Pd/Au) was studied. The Pd films were prepared by electron beam evaporation and oxygen reduction was studied in 0.1 M HClO 4 and 0.05 M H 2 SO 4 solutions using the rotati

The oxygen electroreduction reaction (OERR) kinetics at (111)-and (100)-type Pt electrodes has been studied in aqueous 1.0 M H2SO, solutions in the 8-62ยฐC range. On both Pt electrodes and at all temperatures, two Tafel regions have been observed. The Tafel slope in the low current density range is -
Periodic potentiostatic current/potential curves have been measured at 30ยฐC on platinumgold alloys with gold contents from 5 to 70 at. % in N HsS04 and N HCIOp at 30 and 300 mV/s. The curves exhibit a characteristic shape with two reduction waves during the cathodic sweep, To a first approximation t
