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

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 ...

Platinum-Based Oxygen Reduction Electrocatalysts

Accounts of Chemical Research, 2013
An efficient oxygen reduction reaction (ORR) offers the potential for clean energy generation in low-temperature, proton-exchange membrane fuel cells running on hydrogen fuel and air. In the past several years, researchers have developed high-performance electrocatalysts for the ORR to address the obstacles of high cost of the Pt catalyst per kilowatt ...

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 ...

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
