Abstract
A series of dual-cylinder microelectrodes with different interelectrod e gap were constructed with 7 mu m diameter carbon fibers. The collect ion-efficiency, feedback and shielding properties were studied in deta il with cyclic voltammetry and chronoamperometry for the case of the f errocyanide(III/II) couple. The effect of the collector potential on t he collection-efficiency and the currents at the anode and cathode ele ctrode were discussed. The application of these dual-cylinder microele ctrodes to determine the electrochemical reaction mechanism was demons trated.
