Ultrasonic effects on the electro-reduction of oxygen at a glassy carbon anthraquinone-modified electrode. The Koutecky-Levich equation applied to insonated electro-catalytic reactions
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...

| সংক্ষিপ্ত: | 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. |
