Wr. Fawcett et al., The role of charge distribution in the reactant and product in double layer effects for simple heterogeneous redox reactions, J ELEC CHEM, 498(1-2), 2001, pp. 93-104
The role of charge distribution in transition metal complexes is considered
for simple heterogeneous electron transfer reactions. On the basis of quan
tum chemical calculations for the couples [Co(NH3)(6)](3+/2+), [Fe(H2O)(6)]
(3+/2+), and Fe(CN)(6)(3-/4-), and a simple model for the double layer, it
is shown that the double layer effect for these reactions depends more on t
he charge on the ligands than on that on the central metal ion. The results
of calculations based on the double layer model are discussed with respect
to experimental data obtained at mercury and single crystal gold electrode
