abstract = "The kinetics of O2 reduction on the Au (100) single crystal electrode have been examined in alkaline electrolytes using the rotating dise method. A comparison has been made with the Au (110) and Au (111) surfaces. The quality of the surfaces has been determined by Auger electron spectroscopy and LEED. A pronounced effect of the crystallographic orientation on the kinetics and mechanism of O2 reduction has been found. The half-wave potential for the Au (100) face is the most positive. O2 reduction, only on this surface, proceeds with the exchange of four electrons in a "series" pathway in the potential region of AuOH formation. The cathodic and anodic kinetic data for the O2/HO2- and HO2-/OH- couples support the mechanism O2+e-→ O2- (ads) 2 O2- (ads)+H2O HO2-+O2+OH- Further reduction of HO2- is controlled by an initial one-electron transfer: HO2-+e-+H2O→ 2 OH-+OH(ads) OH(ads)+e- OH- The OH species adsorbed on the Au (100) face appears considerably discharged. Such a surface apparently interacts more strongly with O2, O2- and HO2-, and is probably the origin of the high activity of the Au (100) face for O2 and HO2- reduction.",
