Electrocatalysis with monolayer modified highly organized macroporous electrodes

For the first time the inner surface of highly organized macroporous electrodes, obtained by electrodeposition of gold into the interstitial spaces of a self-assembled close packed array of latex beads, is modified with a monolayer of a catalyst. The combination of the increased specific surface area of these electrodes and the high catalytic rate constant of the redox mediator allows us to construct surfaces showing good elect rocatalytic efficiency. As a model system the electrooxidation of NADH using nitrofluorenone mediators is studied. (C) 2003 Elsevier B.V. All rights reserved.
