On the nm self-assembled Au electrodes and their application to H2O2 calalytic oxidation

The monomolecular-layer self-assembly of nm particle-goldsol on the surface of platinum electrodes and the electrochemical absorption properties of K3Fe(CN)6 on the surface of goldsol are investigated.It is observed that the triple-electrode consisting of the goldsol-dressing electrode as the working electrode,the platinum electrodes as the couplet electrodes and the Ag/AgCl electrode as the reference electrode executes good catalytic oxidation on H2O2,which maintains the good linear relationship with the peak current at the peak oxidation.This discovery is likely to suggest new applications of nm self-assembled dressing electrodes in the fields of electrochemistry and biological catalytic reactions.
