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 characteristics of the ccrium(Iv) reduction have been examined at gold, glassy carbon and iridium rotating disk electrodes in 1 M sulphuric acid. Kinetic parameters have been evaluated from the reduction waves and are found to be independent of the electrode material. Cyclic voltammetric and rad
The double layer capacitance was measured on gold-bead electrodes in N,-stirred 2 N Na,SO, solution as a function of the pre-treatment of the gold surface. Such measurements are sensitive to small quantities of adsorbed oxygen. It is suggested that oxygen may be adsorbed in rather small quantities o
The absorption and reaction of oxygen in aqueous alkaline solutions of sodium dithionite has been experimentally investigated in a novel gas-liquid contactor. The novel gas-lift bubble column contactor was used to study the kinetics over wide ranges of reactant concentrations, temperature, and pH. T
The kinetics of oxygen reduction at Pt in trifluoromethanesulphonic acid (TFMSA) (0.05-6.0 M) and in 1.0 M TFMSA with addition of small concentrations of phosphoric acid (0.003-0.1 M) was investigated using the rrde technique. In TFMSA, the oxygen reduction current on the oxide-covered Pt was found
