How Do Different Ions Influence Catalytic Reactions?
The type of ions present in the electrolyte can play a significant role in catalytic processes. Cations and anions can specifically adsorb onto the catalyst surface, modifying its electronic properties and reactivity. For instance, in oxygen reduction reactions (ORR), the presence of certain cations like Na+ and K+ can either enhance or inhibit the activity of the catalyst. Similarly, halide ions can affect the stability and activity of metal catalysts by forming complexes or altering the surface chemistry.
