Electrochemical Oxygen Reduction Reaction

, 2014
In this chapter, the fundamentals of oxygen reduction reaction (ORR) including thermodynamics and electrode kinetics are presented. The ORR kinetics including reaction mechanisms catalyzed by different electrode materials and catalysts including Pt, Pt alloys, carbon materials, and nonnoble metal catalysts are discussed based on the literature in terms

On the reduction of oxygen in dimethylformamide

Journal of Electroanalytical Chemistry, 1976
Abstract The first reduction process in dimethylformamide containing 0.1 M tetraethylam-moniumperchlorate was studied. The techniques of polarography, controlled potential coulometry and potential sweep voltammetry were applied. The results obtained are consistent with the hypothesis that some chemical reactions are involved in the overall electrode ...

Oxygen Reduction on Sulphide Minerals

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1975
Sulphide ores constitute the major economic source of nonferrous base metals. The reasons for interest in the electrochemistry of the sulphide minerals in such ores have been dealt with by Peters (1) elsewhere in this volume. Briefly, electrochemical mechanisms underlie many processes of practical importance in metal recovery from sulphides, such as ...

Oxygen reduction on iron—IV. The reduction of hydrogen peroxide as the intermediate in oxygen reduction reaction in alkaline solutions

Electrochimica Acta, 1991
Abstract The kinetics of hydrogen peroxide reduction were studied on iron in borate buffered and unbuffered solutions of pH ranging from 8.6 to 13.8, with and without the presence of chloride ions. A rotating disk electrode was employed. Measurements were taken using the linear sweep technique and the potential step steady-state technique.

Electroanalysis of oxygen reduction

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1980
Abstract Fe(III) tetra-(o-aminophenyl)porphyrin and Fe(III) tetra-(N-(2-hydroxyethyl)pyridyl)-porphyrin were attached to glassy carbon electrodes through amidization or esterifification of the methyl acryl chloride polymer. Long-term stability as well as high coverage (up to 10−9 mol cm−2) enabled these electrodes to be useful with respect to ...

Oxygen Reduction Reaction

2020
Polymer electrolyte membrane fuel cells (PEMFCs) and metal air batteries are considered green and efficient electrochemical energy devices and both include reduction of oxygen at cathode during the working of device. Due to the sluggish reaction kinetics of ORR, it is considered the performance limiting factor and to cope with this issue scientists are
