A~traet--CO~ reacts in acid solutions with chemisorbed hydrogen on platinum in the potential range of Eh = 0-250 mV to form a chemisorption product of reduced COs (perhaps CO). The rate of reduction on bright platinum at room temperature is very slow, taking more than 2 min at Eh = 0 for the total
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 8-62Β°C 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 -
