Oxygen reduction has been studied at silver electrodes in alkaline solutions. &e-treatment of the electrodes significantly affects the kinetics of the reduction. At the pre-reduced electrodes, the rate-determining step at high cds is the first discharge step. At low cds, the rate-determining step ch
The steady-state reduction ofoxygen in O,-saturated 2 N H,SO, solution was obtalned at constant current on the front side of a Pt fo11 diaphragm before and after strong anodization of the back side. Strong anodization converts the Pt to a Pt-0 alloy. In all cases, the overvoltage for O2 reduction wa

Metallized membrane electrodes have recently been incorporated into analytical devices for monitoring the oxygen content of atmospheres. This paper describes a simple model for this type of electrode structure and shows that it applies well to the conditions used in an analytical device. The diffusi
