Template Preparation of Nanoelectrode Ensembles - Achieving the 'Pure-Radial'Electrochemical-Response Limiting Case

摘要

We have been investigating a new method for preparing ensembles of disk-shapednanoscopic electrodes. This method entails deposition of the electrode material into the pores of a nanoporous membrane. Nanoscopic wires of the electrode material, with monodisperse diameters, are obtained in each pore. The ends of these nanowires (at one face of the membrane) define the ensemble of disk-shaped nanoelectrodes. We call this approach for preparing nanoelectrode ensembles (NEEs) the template method. In all of our prior investigations the electrode elements in the NEE were so close together that the diffusion layers at the
