摘要

It has been demonstrated that the electrolyte of electropolymerisation of Poly(3,4- ethylenedioxythiophene)(PEDOT) have a significant influence on the electro-catalytic activity forreduction of oxygen. It is notable that PEDOT-modified electrode via electropolymerisation in ionicliquid (GC/PEDOTIL) possesses remarkable electrocatalytic properties for oxygen reduction reaction(ORR) as compared with the electrode obtained from aqueous solution (GC/PEDOTaq). The exchangecurrent densities have been achieved to be 86:1, it indicates the excellent catalytic properties ofGC/PEDOTIL. Nevertheless, the number of electron transferred by per O2 molecule(n) calculated from /2 the slope of the Koutecky-Levich plots [J vs 蠅 ] is to be 2, it means the ORR proceeds via the 2- electron pathway only in alkaline media on PEDOT decorated electrode.
