Influence of the alkali metal cations on the activity of Pt(1Â 1Â 1) towards model electrocatalytic reactions in acidic sulfuric media

- Electrocatalytic activity of Pt(1 1 1) in presence of alkali metal cations.
- Specifically adsorbed (bi)sulfates and cations influence the activity.
- Pt(1 1 1) in Rb+ containing electrolytes demonstrate higher activities.
