    • The CV was baseline corrected by subtraction of a background CV obtained with uncomplexed 2,9-Me2-phen adsorbed onto an EPG electrode. Manually setting a baseline by visual inspection yielded similar results.

    • 2 delivery to the electrode was achieved by rotating the electrode at 100 rpm. This is explored in more detail later to quantify kinetic currents.

    • The kinetic current due to O2 reduction to H2O 2 at -150 mV vs NHE at a 0.195 cm2 electrode in a standard pH 4.8, 20 mM AcO-/20 mM AcOH buffer solution was determined from a Koutecky-Levich analysis to be -26 μA. Upon adsorption of ca. 5 x 10 -10 mol/cm2 of Cu(phen) to the same electrode, the resulting kinetic current due to O2 reduction to H2O was determined to be -347 μA, so the kinetic current due to O2 reduction to H2O2 was ca. 8, Similarly, Anson and colleagues reported less than 6% peroxide generation at -60 mV vs. NHE and fast rotations rates at EPG electrodes with adsorbed Cuphen, ref 8
