Dynamics of the coordination equilibria in solutions containing copper(II), copper(I), and 2,9-dimethyl-1,10-phenanthroline and their effect on the reduction of O2 by Cu(I)

The rates of establishment of coordination equilibria in solutions containing 2,9-dimethyl-1,10-phenanthroline (DMP) and Cu(II) when the latter is reduced to Cu(I) at electrodes were measured by means of cyclic voltammetry. Formal potentials for the Cu(DMP)2+/+ and Cu(DMP)22+/+ couples were evaluated (0.08 and 0.35 V vs SCE, respectively) from which the equilibrium constants for the formation of the Cu(DMP)+ and Cu(DMP)2+ complexes were calculated (6.7 × 108 M-1 and 1.5 × 1010 M-2, respectively). Cu(DMP)2+ is not oxidized by O2, but Cu(DMP)+, generated by addition of Cu2+ to solutions of Cu(DMP)2+, is oxidized by O2. A rate law is presented that accounts for the observed second-order dependences of the reaction rate on [Cu2+], [Cu(DMP)2+], and [Cu(DMP)2+]-1. The stoichiometric reduction of O2 by Cu(DMP)+ in solution is contrasted with the catalytic reduction of O2 by the same complex adsorbed on graphite electrodes.
