AB  - Oxygen reduction has been studied in 0.1 M HClO4 on the platinum low index surfaces, employing a hanging meniscus rotating-disk technique. A special cleaning procedure has been developed to remove impurities from the surface prior to the oxygen reduction measurements. Oxygen reduction was found to be sensitive to the crystallographic orientation of the platinum electrode surface. The activity for oxygen reduction discerned from the half-wave potential decreases in the sequence (110) & >; (111) & >; (100). The reaction proceeds on all well-ordered low index planes with exchange of four electrons per O2 molecule. Tafel slopes of −120 mV per decade at high current densities and −60 mV / per decade at low current densities were found for all three planes at room temperature. Oxygen-containing species chemisorbed on platinum appear to be the cause of the change in the Tafel slope.

AB  - Optical specular reflection is finding extensive use for studies of electrode-electrolyte interfaces. The purpose of this Note is to call attention to the use of complex plane analysis to obtain kinetic information concerning adsorption-desorption processes from the real and imaginary components of p as functions of the ac frequency.

AB  - Vapor-deposited metal-film electrodes on smooth glass substrates are attractive for optical reflectance studies of electrochemical systems because of the high optical quality of the surface and a ratio of true to apparent area relatively close to unity. With gold, the double layer capacity of the vapor-deposited films has been found by the authors to be approximately one-half that observed on mechanically polished electrodes of the bulk metal at the same potentials. Metals such as gold, however, do not adhere well when deposited directly on a glass substrate, and some kind of undercoating generally has been used by various authors in order to obtain adherence, e.g., Paik et aI. used glass Ta-Pt-Au. A number of substances yield adherent vapor-deposited gold films. The purpose of this note is to call attention to the fact that these undercoats can seriously interfere with optical and electrochemical measurements.
