The mediated reduction of oxygen via the reduced form of methyl viologen is studied voltammetrically. The investigation is facilitated through the use of a boron-doped diamond electrode, allowing the catalytic response to be clearly delineated from that of the direct oxygen reduction process at the electrode surface. From simulation a high homogeneous electron transfer rate (6 × 10(9) M(-1) s(-1)) is found for the one-electron reduction of oxygen to superoxide. This value is in close agreement… CONTINUE READING
