Theoretical insight into effect of cation–anion pairs on CO₂ reduction on bismuth electrocatalysts by Sun Hee Yoon (7179263)

“…In the presence of the cation–anion pairs (M⁺/X⁻), Eads of the pairs on hydrated Bi (Bi-2H) becomes more negative than that in the cases of anions or cations alone, particularly when the ionic radius of the paired cation and anion do not differ significantly. Such a synergistic effect of the mixed ions is also observed for the work function values. …”
