Abstract
|
We report the electro-reduction of oxygen in aqueous solution at glassy carbon electrodes modified by the physical adsorption of 1,2-dihydroxyanthraquinone. The catalytic currents are significantly increased under insonation in a manner quantitatively consistent with the increased mass transport as predicted via the Koutecky–Levich equation using diffusion layer thicknesses calculated via studies on well-defined, simple one-electron systems.
