Abstract
Multimolecular layers of 2, 2, 6, 6-tetramethyl-1-piperidinyloxy(TEMPO) was immobilized on a glassy carbon electrode coated with polyacrylic acid. The coverage of TEMPO was about 2x 10-7mol/cm2 and Eo′surf was 0.36V vs. a Ag/Ag+(0.10M) reference electrode. Electrocatalytic oxidation of benzyl alcohol with a TEMPO-modified electrode was observed by cyclic and differential pulse voltammetries. Electrocatalytic current measured by amperometry at an applied potential of 0.45V was linearly increased as the concentration of benzyl alcohol was increased.
