Temperature-dependent oxygen electrochemistry on platinum low-index single crystal surfaces in acid solutions

Temperature-dependent oxygen electrochemistry on platinum low-index single crystal surfaces in acid solutions

Using the rotating ring-disk technique (RRD Pt(hkl) E), the oxygen-reduction reaction (ORR) was studied in sulfuric acid solution over the temperature range 298-333 K At the same temperature, the exchange current density increased in the order, which gives the order of absolute kinetic activities of...

Zusammenfassung:Using the rotating ring-disk technique (RRD Pt(hkl) E), the oxygen-reduction reaction (ORR) was studied in sulfuric acid solution over the temperature range 298-333 K At the same temperature, the exchange current density increased in the order, which gives the order of absolute kinetic activities of Pt(hkl) in 0.05 mol/L H 2 SO 4 : Pt(111)
