AB  - The kinetics of oxygen reduction have been studied on Au (100) and vicinal Au (910) and Au (11, 1, 1) faces in 0.1 M NaOH by a rotating disc-ring method. A very high activity of these surfaces for O2 reduction was demonstrated. The reaction involves a four-electron reduction without HO2- reaching the ring electrode in the presence of the AuOH-(1-λ2) layer on the Au (100) surface. At more negative potentials, as θAuOH → 0, a four-electron reduction takes place in an interactive pathway, followed by a two-electron series pathway and, at very large overpotentials, by a four-electron series pathway. The first electron transfer is the rate-determining step for all three faces. For vicinal faces, the region of the four-electron reduction is reduced due to the smaller region of AuOH formation. Evidence for the surface diffusion of HO2- was found from analysis of the disc-ring data. There were also indications for the splitting of the OO bond by AuOH in the region of the four-electron reduction. Maps of the reaction pathways have been constructed.

AB  - Electrochemical oxidation of D-glucose has been studied in 0.1 M NaOH on single crystal platinum electrodes with thirteen different orientations. The reaction rate depends strongly on the crystallographic orientation of the electrode surface. For most of the surfaces investigated, three voltammetric peaks were observed in the potential region of hydrogen adsorption, the double layer region and the region of anodic film formation. The most active surface is Pt(111). The poisoning adsorbates seem to be less strongly adsorbed on this plane than on Pt(100) or Pt(110). The (100) and (111) oriented steps cause a decrease of the activity of Pt(111). A strongly bound species appears to be adsorbed preferentially on the step sites. Its oxidation was found to coincide with the Pt(OH)ads layer formation.
