	abstract = {The deposition of Au and Ag, locally and from bulk soln., on poly(3,4-ethylenedioxythiophene) (PEDOT) was studied. Specifically, PEDOT was electrochem. polymd. onto a glassy carbon (GC) electrode and used for bulk deposition of Au and Ag from their resp. ions dissolved in the soln. as well as for the local deposition of these metals using scanning electrochem. microscopy (SECM). These two sets of expts. were utilized to investigate the difference between Au and Ag electrochem. deposition on PEDOT. In particular, SECM expts., which were conducted by the controlled anodic dissoln. of Au and Ag microelectrodes close to GC/PEDOT, probed the effect of different PEDOT oxidn. states on local deposition. The current-time transients recorded during the deposition, combined with SEM and energy-dispersive x-ray anal. provided insight into the redn. processes. AuCl4- and Ag+ ions were electrochem. reduced at a potential equal to and more neg. than the ions redox potentials (0.4 and 0.2 V, resp.) and more pos. than -0.7 V, where the PEDOT starts transforming into the reduced, i.e. insulating, state. We found that the electroredn. of Ag+ ions was diffusion-controlled and the PEDOT film served as a simple conductor. The redn. of AuCl4- ions was enhanced on GC/PEDOT as compared with bare GC, indicating that PEDOT catalyzes the redn. of AuCl4- to Au. [on SciFinder(R)]},
