Abstract
<p>The redox-electrode reaction of Co(II)(phen)3/Co(III)(phen)3 (phen = 1,10-phenanthroline) in potassium halide solutions was kinetically studied on a Pt(111) single crystal electrode. The formal rate constants were found to depend on the anions and to decrease in the order: F− > Cl− > Br−. It was found that modification of the electrode surface with a monolayer of thiocyanate ion accelerates the heterogeneous electron-transfer reaction, whereas the reaction was retarded by the modification with iodide. These findings are discussed based on the adsorption of anions.</p>
